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.

Copper concentrate quality drivers. CRU data shows that the average copper concentrate grade has declined by 7% since 2007 (from ~27% to ~25% Cu content). The grade of the concentrate is primarily driven by the mineralogy of the copper deposit, as well as the success rate (recovery) of metal during beneficiation.

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.
