Closed circuit grinding consisted of ball mill and cyclone is adopted in the first grinding. This ensures the separation efficiency, particle size and part of qualified concentrate, and it also abandons part of low grade tailings which reduce the grinding volume of medium ore and the loss of metal.
Combined process of magnetic & flotation separation, environment protection
Magnetic separation sorts out the coarse concentrate and tailings, and reduces the working of flotation operation.
Strong magnetic separation and reverse flotation technology, float little and inhibit much, more cost saving
Strong magnetic process recycles fine iron minerals, which can play a dual role of de-sliming and tailings out creating good conditions for flotation. Reverse flotation process system is simple, which can significantly reduce the flotation reagents into pulp and decrease the adverse effect on the flotation process.
