Copper Smelting - Metallurgist & Mineral Processing Engineer

Jan 13, 2021About 100 pounds of matte are premelted to seal the copper well. Since the matte must be at least 1,250° C before insertion of the water-cooled probe, it is heated initially to 1,400° C before being transferred manually in pots to the COS furnace. An arc is struck on the matte surface immediately after charging to prevent freezing in the well.

gold processing - Mining and concentrating | Britannica

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. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).
