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.
The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example complex gold in a sulphide complex of pyrite must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite.
Recovering precious metals such as palladium platinum gold and other valuable metals such as copper lead and silver from electronic waste becomes economically viable only if enough scrap is collected. Such separation takes more technologically advanced and sophisti ed recycling equipment.
The precious metal minerals are mainly gold and silver mines. Mining has more than 20 years of experience in beneficiation for gold and silver mines especially gold ore beneficiation technology. Gold craft and placer gold selection craft etc.
