Uses of Gold in the Ancient World. Gold was among the first metals to be mined because it commonly occurs in its native form, that is, not combined with other elements, because it is beautiful and imperishable, and because exquisite objects can be made from it. Artisans of ancient civilizations used gold lavishly in decorating tombs and temples, and gold …

A number of different methods can be used to separate gold from its ore, but one of the more common methods is called gold cyanidation. In the process of gold cyanidation, the ore is crushed and then cyanide ((text{CN}^{-})) solution is added so that the gold particles are chemically separated from the ore. In this stage of the process, gold ...
