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.
