The process is carried out in a series of tanks. As the lead and zinc minerals are less readily wetted than the gangue, they adhere to the air bubbles which are carried to the surface. The rock particles sink and the lead and zinc ores are skimmed off. Then the lead ore is separated from the zinc ore. A chemical called a depressant is added

The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth''s surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods. Once it''s removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization

Cadmium: processing; Mining and beneficiation; Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. The mined zinc ores are crushed and ground to liberate the zinc sulfide particles from the waste host rock. The ground ore is usually treated by a differential flotation process to separate the zincbearing particles from the waste rock
