12.3 Primary Copper Smelting

In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.

Copper Mining and Processing: Processing of Copper Ores ...

The primary production of sulfide concentrates includes smelting to copper matte or blister copper, conversion of matte to blister copper, and refining to copper. Smelting, converting, and fire-refining can use a limited amount of secondary materials. Molten copper can effectively dissolve many metals, from valuable noble metals to harmful impurities such as bismuth.

A crusher's wear parts need to last as long as operationally-economically possible. Typical numbers are for liner and mantles to have a useful wear-life of almost 2,000,000 tonne on abrasive taconite and 9,000,000 tonnes on porphyry copper ores. Dependability and long service life are landmarks of good primary crusher design of up to 30 yrs.

Primary Crusher Selection & Design

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
