Aug 07, 2013 Once the borax melts, it lowers the melting temperatures of everything in the ore. As all of the minerals melt down, they separate from one another. As the process continues, the borax causes the other minerals to oxidize and breakdown even further. Gold is unaffected by this reaction and sinks to the bottom of the mixture, intact.
Recovering fine gold from black sands is one of the most challenging aspects of gold mining.

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. 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.
So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier.
