Copper ores - Danafloat

A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silicate minerals from quartz to talc and clays.

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, …


The increased export earnings for bauxite, copper (refined) and nickel (ore and concentrates) generally correlated with increased export volumes (Table 12). In contrast, increased export earnings for diamonds (gem), gold and iron ore in 2019 were the result of higher prices as there were no significant changes in export volume for gold and iron ...

Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters.


gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified.
