Polymetallic Flotation Equipment - Complete Ore Process Plant

This ore processing plant is for the flotation of 2 base metals (Cu/Pb/Zn/Co/Ni/etc.) which may or may not contain precious metals. These ore deposits are called polymetallic by geologists and metallurgists. This system allows you to recovery by way of differential or sequential flotatio, the sulphide metals in 2 separate concentrates. Examples include: Copper, Lead, Zinc, Cobalt, Nickel ...

「hydrocyclone assembly for pyrite mining」

The hydrocyclone overflow is sent for intermediate flotation. Its tails are sent for classification in the battery, which consists of six hydrocyclones. The hydrocyclone sands go to the secondary ball mill, which, together with the hydrocyclone, operate in a closed cycle. The hydrocyclone overflow is considered ready pulp for flotation.
