Copper Mining in the Eyes of Miners. According to miners in southern Peru, mined copper is mainly sold raw as it is more profitable for small-scale and artisanal miners, given that a quantity of at least 100 tons is required to make it into concentrate, apart from paying rent for the use of the plant.

A global copper mine-by-mine review undertaken by ICSG found that the global average copper ore grade was as low as 0.45% copper in reported reserves and only 0.65% copper in 2015 copper mine production. Global weighted average of copper concentrate output in a large sample of plants was around 25% copper in 2015 data.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
