Innovations: How Do They Do That? How Copper is Made

Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.

Heap leaching - Wikipedia

This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.
