The re-smelting process makes it possible to refine one kilogram of iron by using only 2-3 kilograms of charcoal; the burning time is approximately 30 minutes. This is considerably less wasteful than processing by folding. Also, the iron's weight loss is considerably lower compared to fold-processing.

The procedure is accomplished in three ways: refining by fire, by electrolytic, or by chemical methods. Fire refining Iron, copper, and lead are fire-refined by selective oxidation. In this process, oxygen or air is added to the impure liquid metal; the impurities oxidize before the metal and are removed as an oxide slag or a volatile oxide gas.

Iron Element Production and Refining Iron is produced in the United States chiefly from oxide ores. In the Aston process pig iron is refined in a Bessemer converter and then poured into molten iron silicate slag. The resulting semisolid mass is passed between rollers that squeee out most of the slag. The wrought iron has a fibrous

 · The process of refining a metal consists of purifying an impure sample of metal, wherein the final material has similar chemical properties to the original material, but is purer in its composition.
