Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Smelting

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Roasting in Metallurgy

 · In metallurgy, the operation of roasting, as a preliminary to chlorination, has for its object the expulsion of the sulphur, arsenic, antimony and other volatile substances existing in the ore, and the oxidation of the metals left behind, so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in aqueous solution.

Mineral Processing Solutions

Zinc (Zn) is the fourth-most widely used metal, following iron, aluminum and copper. It is mined mostly in Canada, the former USSR, Australia, Peru, Mexico and the US. The US is the world''s largest consumer of zinc. Zinc is a metallic element that has only moderate hardness and can be made ductile and easily worked at moderate temperatures.
