Jordan: Ancient Metallurgy - Division of Social Sciences

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.)

Smelting - Simple English Wikipedia, the free encyclopedia

Smelting is the general term for getting a metal from its natural ore. Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.

Smelting - Revolvy

Smelting is a form of extractive metallurgy; its main use is to produce a base metal from its ore.This includes production of silver, iron, copper and other base metals from their ores. Smelting makes use of heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving just the metal base behind. The reducing agent is commonly a source of ...
