Lead Essential Chemical Industry

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.

How gold is made history, used, parts, procedure

Separating the gold from the ore. Smelting involves heating the gold with a chemical substance called flux. The flux bonds with the contaminants and floats on top of the melted gold. The gold is then cooled and allowed to harden in molds, and the flux contaminant mixture (slag) is hauled away as a solid waste.
