  • The method of extraction of gold from cyanide solutions

    (57) Abstract: Use: for the extraction of gold from its cyanide salts in the waste and wastewater. The bottom line: the recovery of gold from cyanide solutions by electrolysis is conducted so that before the electrolysis of a concentrated alkaline solution containing hydroxide is not less than 1.5 gEQ/l is treated with hydrochloric acid to a

  • Cyanide Chemistry Gold Extraction

    The fact that many millions of gold have been extracted by the cyanide process, during the last five or six years, from South African tailings which could not be profitably worked by any other method previously tried upon them, lends a peculiar practical interest to this branch of metallurgy.

  • Method of Gold Extraction using Borax Small Scale Miners

    Eliminate Mercury using this method of gold extraction with borax for smallscale miners allows for fine gold recovery and better smelting. Excess mercury is recovered, and by blowtorching the remaining bit of amalgam, the mercury evaporates leaving behind the gold. Leach Gold Without Cyanide.

  • Process of Cyanide Gold Extraction

    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.
