Diamonds Found in Black Sand

Gold Panners focus is always to recover as much gold as they can. The sluice box is usually the tool of choice, but do you carefully check your black sand for diamonds? Those funny quartz rocks that get caught around the black sand areas at the end of the sluice.

On occasion I get reports from miners that they get what appears to be quartz rocks trapped in the black sand in their boxes, but, these rocks don't look the same as the other pieces of quartz.

When you are checking your sluice box for fine gold please check the black sand areas for diamonds.

What to look for:

- These stones will be at the very end of your sluice box, just past the black sand areas.

- Diamonds don't wet like normal stones. Water will bead up and roll off these stones as if they had a Vaseline coating.

- Diamonds come in a range of colors from clear to dark as well as blue and pink.

- They may have bits of rock attached to them indicating they haven't traveled far from their kimberlite source.

It is also worth mentioning that diamonds are worth a lot of money - even the dark ones. One stone can go for $5,000 easily so it is worth watching for these occasional wonders. It is like finding a treasure in your sluice box.

Froth Flotation Separation processing

Froth Flotation Separation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. Sulfide and non-sulfide minerals as well as native metals are recovered by Froth Flotation Separation. This process is based on the ability of certain chemicals to modify the surface properties of the mineral(s). Other chemicals are used to generate the froth and still others are used to adjust the pH. Certain chemicals are even capable of depressing the flotation of minerals that are either to be recovered at a later time or are not to be recovered.

The process of Froth Flotation Separation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp. The pulp is processed in the flotation cells, which agitate the mixture and introduce air as small bubbles.

The ability of a mineral to float depends upon its surface properties. Chemical modification of these properties enables the mineral particles to attach to an air bubble in the flotation cell. The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell. Even though the air bubbles often break at this point, the mineral remains on the surface of the froth. The mineral is physically separated from the remaining pulp material and is removed for further processing.

Tips for Successful Gold Detecting

Dig Everything (At least at first) Many goldfields are absolutely littered with iron rubbish; rusty nails, boot tacks, bullets, old cans, miscellaneous iron fragments, etc. There may be hundreds or even thousands of iron trash targets for every piece of detectable gold. This can seem overwhelming for a beginner (and even experienced) detectorists. It can be easy to get lazy and start depending too much on your detectors discrimination features so that you do not have to dig so many holes. At first, you should really dig every target, regardless of what it sounds like or what you think it might be. Learn the sounds that your detector makes before trying to pass over targets. As you gain experience with your detector you can start to reevaluate what targets are worth digging and which ones are not.

Choose the proper search coil Most metal detectors have several different shapes and sizes of search coils that can be used on each detector. Depending on the area that you are prospecting, different types of search coils should be used. Mono coils will generally locate targets deeper than DD coils, but will not discriminate targets in the same ways. Larger coils are ideal for finding larger, deeper nuggets in areas that have been hunted by previous detectorists, but sometimes a smaller coil will operate more smoothly in highly mineralized ground. Do not be afraid to experiment with different coils in different areas.

Slow down your sweep speed Most gold nuggets are small and give off a subtle target sound. Swinging your detector too quickly will increase ground noise and mask the sound of a gold nugget. Keep your search coil close to the ground and slow down your speed to increase the chances of hearing a nugget.

Scheelite Concentrate Plant

China is the big country with tungsten resources, accounting for 51% of tungsten ore reserves of the world. Nature of tungsten have been found more than 20 kinds of minerals, of which the largest is the industrial value of scheelite and wolframite, and wolframite after a long period of mining, which has been slightly less conservative reserves, so this part is only for scheelite ore resources sorting and research.

Scheelite (CaWO4) is a calcium tungsten, whose chemical composition of WO3 80.6%, CaO 16.4%. Scheelite more brittle toughness, hardness is generally 5 to 5.5, a density of 6.8, non-magnetic, the color is white. From the beginning of the 1970s, scheelite flotation has made great progress, most have adopted the flotation processing plant, such as Tempe Utes, Samdhong, Jiu Ke, Golden Island, and other selected plants have adopted the flotation process plant.

Last few days, one of our clients from Korea that visited our factory for their scheelite recover processing plant. They mining the scheelite rock from mine area also recycle the waste rock from that a few years before. XTA machine is best to sorting the rock. The better rock will use crushing, grinding then use gravity concentrate plant to concentrate it, after the gravity processing plant, they get the scheelite with more than 65% purity WO3. Then use the wet type magnetic separator to separate the magnetite iron. After the magnetic separation plant, they will use the flotation machine to concentrate again to separate the As from the concentrate. The plant with full design and all use the best quality equipment. They come to our factory check and confirmed our spiral and shaking table. The spirals is big capacity for the rough of the scheelite, and use the shaking table to concentrate it again. Their capacity required is 80t/h, so we design a plant for 16 pics spirals to do it, and they choose the double gold shaking table to concentrate it. After their order, our machinery technical will go to their mine area for the installation guidance in Korea.

Tantalum-niobium ore beneficiation process

Tantalum-niobium ore beneficiation roughing use the gravity concentrate equipment, the concentrate re-election usually combined with gravity plant, gold flotation plant, electric magnetic separation or smelting etc. If processing fine raw ore or with many mud, the washing plant is necessary, while using efficient grinding and classification equipment to reduce mineral mud of tantalum-niobium.

Overseas there are so many tantalum-niobium ore mine area use the trommel washing screen or scrubber to wash the raw ore and grinding by ball mill with the classifier, like as the Australian Green Booth pegmatite mine alluvial clay weathered rough processing plant. The Canada Bonike Lake tantalum ore through continuous improvement, grinding process currently used is quite distinctive. Overseas ore ore for tantalum and niobium rougher still re-election based and gravity plant with an efficient, simple process. Like as in Green Booth mine area use the jig separator to concentrate the tantalum-niobium. As the gravity concentrate plant, the spiral classifier and gold shaking table is the best machine for tantalum-niobium concentrate.

China the grade of tantalum-niobium ore is generally low, and its mineral crisp, high density. In order to ensure the grinding fineness, to avoid over-grinding, the general stage grinding stage sorting process. Jiangxi Yichun tantalum-niobium concentrate using lateral curved screen replace linear vibrating screen for screening, field exploration results showed that: a fine sieve can be reduced 14.70 percent clip, clip rough can be reduced 4.3 percent next screen, screening efficiency can be increased 17.72 %. Successfully tested the device for on-site screening stage grinding transformation provides a new way. In recent years, China has made some progress in the study of tantalum and niobium flotation plant, but because the drug prices are too high, only a few overseas tantalum-niobium mine use flotation method, such as Canada Oka, Brazil Allah Aqsa mine areas.

Crushing plant for rock ore processing

The purpose of ore crushing and grinding is grinding and size classification to reduce the ore down to a fine particle size. Generally the complete ore crushing plant consists of jaw crusher, ball mill classifier, magnetic separator, flotation machines, thickener, dryers and other major equipment, such as vibrating feeder, bucket elevator and belt conveyor. This production line feature with high efficiency, low energy, high capacity, economical and so on.

The primary crusher reduces ore from the trucks to 8-inches or less. That material goes to the primary stock pile directly that you see crushed rock falling onto in your image. Two conveyors (out of view to the right in your image) pull this material directly into each SAG mill where it is combined with water and mill balls (as needed). Big raw ores are feed to the jaw crusher evenly and gradually by vibrating feeder machine for primary crushing.

After primary crushing, the material will be transferred to other crushers by belt conveyor for secondary crushing, and then the crushed materials will be transferred to vibrating screen for separating. Final, the materials will be transferred into the ball mill evenly for ore grinding.

Flotation machine - JXSC mine machinery factory

                  

The flotation machine’s impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board.

When Gold ore flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air sent by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remaining slurry flows to the next trough until it becomes residue.

Chromite ore concentrate plant design

Recently more and more clients asked to our factory about the chromite ore Gold Concentration Plant design question. About the chromite ore separation processing, that’s depend on the grade of the chromite ore. If you need concentrate better chromite ore, that you need use more equipments to concentrate it. Chromite ore is famous mineral that for the steel manufacture, use the chromite in steel, the steel get better quality and hardness. So it’s one of the best mineral for metal materials.

As our engineers experiences, gravity concentrate plant is the best one. If the chromite ore is rock, so the crushing is first part of the plant, use the coarse jaw crusher and fine jaw crusher to crushing the rock and get small size that can put into the ball mill to griding very fine particle. After the griding by ball mill, fine size go to the mixing tank with water and goes to the spiral chute to concentrate the chromite concentrate. In our whole plant, the bigger size from ball mill, will screening by the vibrating screen to get small fine size, if the size too big, they will back to ball mill griding again, to make sure the best fine particle size. Our spiral is the best plant for gravity concentrate plant, it’s made by high quality fiberglass with polyurethane coating. The high ratio of recovery is very well, and running without power, economic. The spiral to concentrate the chromite ore that you can get the best high grade chromite ore.

Our complete chromite is the best one plant, we also can supply different plant for chromite, that’s depend on your raw chromite ore situation and details. If you also want to purchase any equipments to recover the chromite, please contact our factory, and welcome to our factory for a visit.

Gravity plant concentrate lead and copper in Iran

Recently one of our customer from Iran want to build a gravity Centrifugal gold concentrator plant for the lead and copper. The customer has 2 mine area, all of them is the rock ore. The first one is rock lead ore, the analysis report shows the lead ore with 3.2% lead and 27g/t silver grade. And the other copper ore with 8.54% copper, 32g/t silver. These 2 mine area is rich of lead and copper. The customer want to choose the gravity concentrate plant, caused the gravity plant is more environmental friendly plant than flotation concentrate plant.

As their purpose, they want to get the lead at least up grade to 20% copper concentrate,  50% lead concentrate and get silver concentrate from the tailings. As our engineers experience is just a few difficult to up the grade concentrate. According this situation our engineers talked so much and finally have a plant design flowchart drawing. We configurated the plant including crushing part, grinding part, classifier part and concentrate part. For the plant design our engineers discussion, the gravity plant calculate get the concentrate lead around 25-40%, and the copper concentrate about 18%. The plant including use coarse jaw crusher, fine jaw crusher, ball mill, spiral classifier and shaking table. Use the ball mill can get the fine particle size less than 0.074mm, and the shaking table use the fine deck to get the concentrate lead and copper.

Our customer is interest in our plant, and they will have a factory visit. Before the order, they also need get more information from our factory, especially in gravity plant concentrate, our factory have many years in this field, so we can do the best for our customer. I’d like to looking forward to meet our customer and have a meeting with our engineers to get confirmation for the plant design.

Iron ore dressing plant, iron jig gravity separator, iron jig washer

There are magnetic iron ore like magnetite and weak magnetic iron ore like liminite, hematite, specularite, and for these two kinds of different iron ore, different upgrading way will be involved. For manganetic iron ore, magnetic separator is prior to be considered to get the high grade iron concentrate. But if magnetic separation is still used for the weak magnetic iron beneficiation, a large plant investment will be needed because it needs strong intensity Iron ore magnetic separator to work. However, here gravity separation can also work for the weak magnetic iron ore. So when the gravity separation can be used? Firstly, the inlay size of iron granules shall be coarse with clear bounds with the other gangue, and crushing can dissociate the iron grain from the raw gangue. Second, there shall be density difference between the iron granules and the other inlayed gangue. On both conditions, the iron ore can be upgrading by gravity separation machine. Here the iron jig machine has been introduced as the ideal separation gravity separation for weak magnetic iron ore. Test can be done if samples about 15kg can be available.

Portable design alluvial gold concentrate plant for Indonesia

Recently, our factory just finished one set plant for alluvial gold concentrate plant with portable design for our customer in Indonesia. The customer with a big alluvial gold mine area, and they want to purchase one plant for the gold recovery and convenience to mobile one site to others size. So our factory have more many years experience in gold concentrate plant design, and as our engineer suggestion, we complete the plant for you them.

The plant capacity is around 40t/h, not very big, but is mobile one, with the whole plant can be move to different mine area, like as a trailer. If the capacity too much, the design may hard to finish, so if the capacity less than 100t/h, the designing is better to design. At first, our engineer suggested the choose our Small mobile trommel machine, our factory had finished many portable alluvial gold concentrate plant before. Concern about their raw ore does not with any sticky clay, so the trommel screen is enough, don’t need the scrubber part. The whole plant is contents with gold trommel screen, gold centrifuge concentrator, shaking table, sluice, pump and others pipe connection parts.

For the plant design, in the primary washing part, there with a hopper with grizzly feeder that can remove too big gravel, then the trommel screen with can process and screening the small size goes to the centrifuge concentrator by pumping. In the second part is the gold centrifuge concentrator and shaking table, they are on one platform, and design with by wheels. The concentrate after the centrifuge concentrate process will goes to the shaking table concentrate again to get the high purity gold dust. About the tailing from the centrifuge concentrator if there with some waste of gold, it recycled by the sluice box, the sluice box is the best one for tailing concentrate, so the plant is the best one to protect the gold waste. Our customer is very enjoying the plant, hope the plant will work well in the mine area.

Nickel ore price doubled

Nickel ore price has continued to rise because of the ban of raw ore exporting in Indonesia, the price of the nickel ore (1.8-1.9%) in China port is 830-850RMB/Ton now, which is doubled compare with the price in January 12^th, when the ban has been practiced.

Indonesia is the main exporter of laterite-nickel, which has occupied over 40% of the total exporting amount in the world in 2013. When the government banned the exporting, it’s means the supply has been reduced 440,000 tons, this is a very bad new for the Chinese nickel related industries.

The laterite-nickel has been used for producing the stainless steel in China, which could replace the nickel metal to reduce the cost. And China is the main importer of the laterite-nickel, in 2013, China has imported 41,099,500 tons nickel, and there was 57.63% from Indonesia. Another 41.67% was imported from Philippines.

The demand is increasing, and the supply is going down sharply, there’s no way to stop the price increasing. The stock in the sea port is going down, and expected to be finished in 8 month..

Another two negative factors are: As the main supplier of nickel metal—Russia has been sanctioned by the EU and USA; and the giant nickel mining plant of Vale have been shut down because of the pollution in last month. The price of nickel is still in the high way.

The basic principle for gravity separation equipment

In the movement media, being loose mineral Particle Swarm, because of differences in settlement movement, the formation of different density (or size) of mineral particle layered. Good bed (that is, material layer composed of particles) through sports media moved to achieve separation. Its basic rules can be summarized as follows: loose-layer-separation. in fact, loose layering and separation of freight is almost always occur simultaneously. But loose is hierarchical conditions, layering is the basis for separation. Is the most basic form of settlement. Loose can be thought of as particles are on the rise in the media stream a special form of settlement.

Design Principles of Laboratory sealed jaw crushers

Laboratory sealed jaw crushers is on medium and fine crushed materials for the purposes of laboratory and production and especially as environmental protection equipment for the coal, electricity, Gold Mining Machine, geology, chemistry, metallurgy -, building materials and other industries. The product is indicated by the only company of the former Ministry of Geology and Mineral Resources, manufactured in accordance with industry standards.

XPC model Sealed Jaw Crusher is a new generation of crushing plants with slightly open dynamic and static jaws, convenient cleaning and without mixing of samples. It is capable of fine and medium refractive a variety of ores and materials having a compressive strength of 24kg/cm2 and down. with large crushing ratio, uniform particle size and setting the output size.

I. Main Design and functional principle

This machine is composed mainly of machine body, movable jaw, eccentric shaft, jaw plate, flywheel, pulley, movable part, motor, hopper and the collecting funnel.

The three angles of motor pulley drive the eccentric shaft through the pulley to get move the movable jaw along the track already adapted to crush as the materials in the crushing chamber.

The machine body is all steel. Fixed jaw plate is mounted on its front wall. Edge plates are provided on the side wall of the frame on the left and right of the crushing chamber, in order to prevent the abrasion of the side wall of the frame, is mounted.

The movable jaw is a form of casting. On the front of active jaw plates are installed. At its peak, the eccentric shaft and bearings hanging over the frame. Your floor is supported on the moving parts and. In rolling contact with the moving parts At the two ends of the eccentric shaft is the flywheel and the pulley is installed at the groove. The machine body is connected to the machine base and the slideway of the motor is fixed onto the machine base with bolts.

The supporting system of moving jaw is equipped with riveting pin connection device. If hard objects that can not be broken (eg pieces of iron) in the materials crushed, ie the crusher is overloaded, the pin will quickly rivering break, play a protective role to preserve other important parts of the crusher from damage.

A grip having a function of angular displacement provided, installed on the left side of the machine. This handle is used to adjust the size of the outlet opening. The distance between the outlet openings can be adjusted by the adjustment of the handle. In addition, when the jaw plate is abraded, the gap between discharge openings can be compensated through the adjustment of the handle.
