How to Separate Precious Metal

The gold should slip down into the smelting vessel. After this occurs, you can cool and remove the gold from the smelting vessel and also remove the slag as well. It's common at this point to refine the gold through a separate refinement process to ensure a high level of purity. Get price

Amalgam (chemistry)

In gold placer mining, in which minute specks of gold are washed from sand or gravel deposits, mercury was often used to separate the gold from other heavy minerals. After all of the practical metal had been taken out from the ore, the mercury was dispensed down a long copper trough, which formed a thin coating of mercury on the exterior. Get price
