12.3 Primary Copper Smelting

Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

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.

History of the Warren (Bisbee) Mining District

Extraction Of Copper | Mining, Concentration, Smelting ...

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of ...

Copper production & environmental impact

• Depending on whether an ore is sulfide or oxide, the process follows one of two routes. Beneficiation • Beneficiation is the concentration of ore through separation into desirable mineral-the part of the ore that is useable; and gangue (pronounced ‘gang’) – the part of the ore that is commercially worthless.
