Some Experiments in Prehistoric Copper Smelting

Some Experiments in Prehistoric Copper Smelting

The first technically meaningful descriptions of copper smelting of sulfide ores occur in the writings of the 15th and 16th centuries (810). What is described are somewhat modified versions of what is called "matte smelting" today. Matte smelting is a multistage pyrometallurgical process from which metal does not emerge until the last step. The first stage is called "roasting" in modern ...

Smelting. Smelting is the basic process by which one produces workable metal from metal ores. The minerals in copper ores are reduced to copper through mixing carbon with the ore and heating the combination to about 1,100°C. (This can be done directly with copper oxide ores. Copper sulphide ores are heated in contact with air first.) At this temperature the metal, now liquid, flows to the ...
