A process is described involving gold in which gold cyanide ion (, potassium gold cyanide) is removed from an aqueous solution (typically a water rinse solution) by absorption on an anionexchange resin and the gold cyanide ion is then removed from the resin using an eluent solution comprising organic solvent, water and thiocyanate ion.
The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery ...
