·The application of pressure oxidation POX followed by thiosulfate gold leaching is an efficient method used to extract gold from double refractory gold ores containing both sulfide and carbonaceous matter This process is expected to result in high gold recovery rates as it liberates gold from sulfides and eliminates the preg robbing behavior of
·An adequate supply of dissolved oxygen must be present in the cyanide solution throughout the reaction period preferably by the atomic absorption technique to obtain rapid gold and silver assays at the plant site When the analyses indicate that the lead charge of carbon has adsorbed the desired amount of gold or becomes saturated a
·While the leaching of silver is chemically analogous to that of gold percentage recovery of silver is less than gold due to a significant slower dissolution reaction rate; however silver usually
·Test results show that % Cu % Zn % Pb % Fe % As and % Sb can be leached from the sulfide ores through these leaching processes And the leaching rates of gold and silver were achieved at % and % respectively in the nickel∠ammonia∠thiosulfate leaching solutions [108]
·More than 83 per cent of the world s gold is extracted via cyanidation because of its convenient operation low cost and high leaching rate However cyanide has a high biological toxicity and poor leaching performance in refractory gold ores containing copper and carbon Nunan et al 2017 Nwaila et al 2019 Hence extensive studies have been conducted on
