When sent for smelting, the copper concentrate and a silica material known as a flux are fed into a Vanyukov furnace. The concentrate and flux melt and make the matte, comprising copper, iron and sulphur that settles at the bottom of the furnace. The rest of the iron chemically combines with the flux to form a slag, which can be separated off.

The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to …
Bottom: Solvent extraction tanks for copper solution leached oxide ore. Sulfide Ore: The dried copper concentrates are sent to the smelting operation where it is reduced and melted in several operations. At the end of this melting process the copper is about 99% pure. While this may sound high, it is still not pure enough for electrical ...
Copper Smelting: To produce bronze, people became adept at smelting copper ores, a process that involves heating copper-rich minerals to high temperatures. Early smelting furnaces were simple clay structures fired with wood or …
