Gold Parting using Nitric Acid

Parting of Copper and Gold. If parting depended on the formula alone, assuming that the alloying metal was dissolved by nitric acid, then copper should do as well as zinc, since the atomic weights are nearly equal. In order to determine this an alloy of 10.008 of gold and 10.080 of copper was made and placed in 1 of nitric to 2 of water and boiled.

By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
