A Poor Man's Method Of Smelting Gold Sciencing

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.Feb 01 1984 Pressure oxidation of gold containing concentrates and ores is an effective pretreatment for liberating refractory gold This is particularly true when an appreciable portion of the gold is associated with sulfides and is not amenable to conventional cyanidation A brief review of the literature on pressure oxidation of refractory gold materials is presented.
