Recently, Han et al. (2018) used an autoclave to study copper leaching from old Bor copper mine flotation waste. The authors found that a H 2 SO 4 concentration of 0.5 M, a pressure of 2 MPa, a temperature of 180 °C, a leaching time of 60 min, and a solid phase content of 400 g/L resulted in a leaching efficiency of 98% of the copper .

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...
