Processing Of Gold And Iron

Egyptian Gold Processing. Print. It is not surprising that gold was the first metal processed by the Egyptians. Very few metals are found in their native state i.e. not bound to other elements in a compound such as a mineral. Copper is very rarely found in nature as an element and iron is typically only found as an element in some meteorites .

    Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia a mixture of hydrochloric and nitric acids and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.

    Gold extracted by amalgamation or cyanidation contains a variety of impurities including zinc copper silver and iron. Two methods are commonly employed for purification the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures equal to or greater than .
