Gold CIL CIP Gold Leaching Process Explained CCD
The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon CIL stands for carboninleach This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching 1 Introduction Berezowsky and Sefton (1979) demonstrated that precious metals in the residue from oxidative leaching of copper sulphide concentrates in ammonia/ammonium sulphate can be subjected to cupric promoted ammoniacal thiosulphate leach Since then, the thiosulphate leaching and recovery of gold and silver has attracted the attention of many researchersGold leaching by copper(II) in ammoniacal For gold ore, it was reported that HPGR shortens the drainage cycle for the leach solutions and hence minimizes the solution inventory time (Baum and Ausburn, 2011, Klingmann, 2005) Also, McNab (2006) reported 10–11% increase in gold leaching due to the HPGR microfracturing effectCrushed ore agglomeration and its control for heap 3 The geochemical behavior of gold in hydrothermal systems The occurrence of gold mainly depends on temperature, pressure, pH values, Cl − concentration, and fugacity of H 2 S in a hydrothermal system Gold mostly occurs as AuCl − 2 in a system with temperature higher than 400 °C (Gammons and WilliamsJones, 1997), and with decreasing temperature being the primary mechanism causing gold Geochemistry of hydrothermal gold deposits: A review The ration of Fe 3+ and Fe 2+ in the biodissolution is widely considered as the main factor for the dissolution of pyrite (Holmes and Crundwell, 2000; Chandra and Gerson, 2010b; Zhang et al, 2020b)Fe 3+ could be used as an oxidant for pyrite and Fe 2+ promote the growth and metabolism of bacteria The greater the proportion of Fe 3+ in the solution results in the higher the redox potential Active destruction of pyrite passivation by ozone
