6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

The tailings of lead flotation come to the agitators. By adding chemicals again to the agitators, it comes to another process of zinc flotation. At this time, the tailings and scavenger concentrate tailings go back to the former stage. The zinc concentrate is separated out in the third beneficiation process, and is sent to the setting pond.

Froth Flotation Process - Detailed Explanation With ...

Thus the sulphide ore comes on the top with the froth and oil. The remaining gangue particles which did not dissolve in oil settle down. The foam is removed and taken for further processing. Thus the minerals are separated by the froth -flotation process. This method is extensively utilized for Copper sulphide, lead sulphide and Zinc sulphide.
