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.

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining.A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as

Zinc is the 16 th most abundant metal and 23 rd most abundant element in earth''s crust, respectively. It is more abundant than copper, although global copper production is considerably more than that of zinc. Global zinc production is primarily from its ore, zinc sulphide, commonly known as sphalerite.
