parting separate gold and silver by meltingparting is the separation of silver from gold and a process during which the base metals are separated from both, but, as the presence of a high percentage of these base metals is injurious to the successful conduct of the processes which are chiefly in use, a preliminary refining by one of the methods already described is usually necessary.

gold parting gold parting is the separating of gold from silver.gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. over the centuries special means of separation have been invented. the very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.with the advent of coinage, methods had to be invented to
