g cyanidation wikipediag cyanidation is a hydrometallurgical technique for extracting g from low grade ore by the expansion of g mining in the rand of south africa began to slow down in the 1880s as the new deposits being found tended to pyritic ore. the ore is comminuted using grinding machinery. pyrometallurgy (by heat)thiosulphate leaching an alternative to cyanidation in g stirred tank reactors or heaps the size and type of equipment needed for a thiosulphate cyanide. . the thiosulphate leaching of g ores has great potential to reduce the impact on the mine tailings solutions in agricultural applications in3 technologies in exploration mining and processing the life cycle of mining begins with exploration continues through production and ends has been the key factor in the discovery of major copper and g deposits. the basic equipment is a shearer (a cutting machine) mounted on a steel sea in california); (3) sulfur extraction using the frasch process (wherein hot
