  • parting | metallurgy | Britannica

    parting, in metallurgy, the separation of gold and silver by chemical or electrochemical means. Gold and silver are often extracted together from the same ores or recovered as by-products from the extraction of other metals. A solid mixture of the two, known as bullion, or doré, can be parted by boiling in nitric acid.The silver is dissolved as silver nitrate, leaving a residue of gold that ...
