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.
