Hematite Separation Process in China

Hematite Separation Process in China

【Process Achievements】Hematite Separation Process

Stage grinding, stage separation and high separation efficiency

The combination of multi process and environmental protection

Strong magnetic separation and reverse flotation process ensure the concentrate grade;

Hematite separation process is suitable for complex structure hematite such as hematite and impurities with uneven distribution of particle size, ore with large content of fine particle, ore with small amount of magnetite and the gangue minerals containing quartz or kaolin.

Stage grinding reduces subsequent operations and costs

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.
