extraction of lead zinc from complex sulphide ores

Complex Sulphide Ores: Processing Options | SpringerLink

Complex sulphide ores represent considerable reserves and resources in base non ferrous metals, in precious metals, and in sulphur. Some of their essential characteristics, which allow a general presentation of the complexity of their processing options, from the ore to the pure metals or finished products, have already been presented by the author (1,2).

Zinc: smelting, producing and classification-Metalpedia

Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from the other minerals. Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible.

Extraction of Zinc | Application Of Zinc Refining Process

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 extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.
