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.

Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90 of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low ...
Oct 15, 2016 As for dissolving the gold that is not what I want, I want to dissolve the pyrite to get the free gold out.
