Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
One process developed in Canada, and capable of recovering 99% of the zinc in the ore, uses pressures in excess of 10 atmospheres and a temperature of ca 420 K. The presence of iron in the ore concentrate is important in this method, as it is in part responsible for the conversion of zinc sulfide to zinc sulfate.

Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is
In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods used today. The Basics of Zinc Mining and Processing
Zinc sulfate, ZnSO 4, is an intermediate compound in the production of zinc from its ores by the electrolytic process. It is used as a weed killer, in the manufacture of viscose rayon , and in dyeing, in which it functions as a mordant.
