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 carboninpulp. 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. Inquire Now

2019-10-1Refractory Gold Any ore that is not readily amenable to recovery by conventional cyanide leaching at a reasonable grind sie can be considered refractory. The three primary factors that cause gold ores to be refractory are Physical encapsulation Extremely fine 10 m particles are locked within an impervious unreactive mineral

Four iron-sulphide-containing gold ores from the White Mountain mine in the Jilin Province China were studied to examine the benefits of using oxidative treatment prior to conventional cyanidation to leach gold. This pre-treatment consisted of bubbling air into an orewater mixture for eight hours while adding enough caustic sodium hydroxide to maintain a pH of 11 throughout the test. Three
