Extraction of Zinc Zinc Mining. The most commonly available ore used in the extraction of zinc is called zinc blende also known as zinc sulphide (ZnS). Historically extraction of zinc has been more difficult than the extraction of other metals because, at temperatures where metals such as iron typically begin to melt, zinc is a gas.

Cinnabar (ore of mercury) means HgS (mercury sulphide). Concentration of ore - this involves grinding of her and separating the unwanted dirt from it. Roasting of ore - as the ore is of sulphide then roasting is to be done this involves the heating of sulphide ore in the Presence of oxygen to form metal oxide and Sulphur dioxide.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores …
