Mercury mixing gold leaching process is a kind of ancient gold process, which is simple and convenient and economical. Mercury mixing gold leaching process is suitable for recycle coarse grain monomer gold but is harmful to environment. So this process is gradually replaced by gravity separation, flotation and cyanidation gold leaching process.

Pachuca aeration gave better gold extraction and lower cyanide consumption than bottle agitation. With the former more copper was found in solution, and less thiocyanate was formed; with bottle agitation the reverse was the case, in addition to which copper cyanogen complexes were found in the filter cake.
