Magnetic separator is the basic tool used by mineral processing plants to separate ferrous and non-ferrous metals from extracted ore, ensuring high-quality final products. Its works by attracting magnetic particles such as iron, steel and nickel, and then using powerful magnets or electromagnets to separate these particles from other materials.

During flotation, too coarse ore particles (greater than 0.1mm) and very fine ore particles (less than 0.006mm) do not float well, and the recovery rate is low. In the flotation of coarse particles, due to the larger weight, the shedding force of the ore particles increases. Then you need: (1) Use a sufficient amount of the most effective ...

The flotation method has a good effect on the recovery of fine-grained limonite. It is best to wash and deslim the limonite before flotation, otherwise, the ore mud will seriously affect the flotation effect. For limonite with single nature, the recovery rate of the flotation method is higher, but the cost is also higher.
