Division of Geology and Mineral Resources - Zinc

Zinc is a bluish-white, lustrous metal with the chemical symbol Zn. Its main ore mineral is sphalerite (ZnS). Some of its uses are for galvanizing (plating thin layers of zinc onto iron or steel to protect from corrosion), production of brass (combination of zinc and copper), and coloring in rubber and paint.

Cost of Producing Concentrates from Ore

From the viewpoint of mineral economics, the ultimate and significant production cost is that per unit of metal produced rather than the cost per ton of ore treated. This viewpoint is natural to processors of ores whose final product is refined or unrefined metal, whether they be companies engaged solely in smelting, or integrated companies engaged in mining, milling, and smelting operations.

Lead and Zinc - Department of Energy

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.

The invention relates to the hydrometallurgical production of zinc from zinc bearing ores and concentrates. The sulphide is the more common form of zinc which creates a problem of atmospheric pollution with sulphur dioxide, but zinc in the form of carbonates and oxides may also be treated by this method and can be treated more efficiently in some cases than the sulphides.
