60 Centuries of Copper: Early Smelting Practice

Early Smelting Practice. Virtually all the ore used by the ancients was handpicked with only the most worthwhile material being taken. Originally it was probably smelted by the Sumerians in shallow pits using charcoal as the fuel. How they first derived the necessary draught to raise the temperature sufficiently to melt the ore is still a matter of speculation, but it may have been done by ...

What Is Metal Smelting? (with pictures)

Metal smelting is the process of creating metal by heating metal ore. The ore, be it iron, copper or tin, is mixed with a carbon and the mixture is heated to the point of conversion into a liquid form. The liquid is then mixed with a flux, such as limestone, when metal smelting. The flux allows all of the impurities formed while metal smelting to be removed from the top of the liquid as slag.
