Extracting Gold | HowStuffWorks

As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon. The carbon moves to a stripping vessel where a hot caustic solution separates the gold from the carbon.

How to Separate Gold From Other Metals at Home?

The most common method used to separate gold from other metals is by using a panning technique. Panning mainly involves swishing water and sediment around in a pan in order to separate the heavier gold particles from lighter ones. This process works best with small pieces of gold, such as flakes or dust.

PARTING: Separate Gold and Silver by Melting

The processes of parting may be tabulated as follows: Cementation. Melting with sulphide of antimony. Melting with sulphur, and precipitation of the gold from the regulus by silver, iron, or litharge. Parting by nitric acid. Parting by sulphuric acid, sometimes called "refining.". A combination of these last two methods.
