Faculty of Materials Engineering, Sahand University of Technology, Tabriz, Iran; 2. Materials and Metallurgical Department, UniversityThe process design of gold leaching and carbon-in-pulp,,Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide.Leaching - an overview | ScienceDirect Topics,Leaching losses are generally assumed to be higher in the humid tropics than temperate areas due to the frequent and intense rain storms, higher temperature, and high carbonic acid content in soil (Ah Tung et al., 2009; Johnson et al., 1975).Depending on the amount of water draining out of the rooting zone, leached solutes may simply accumulate in a deeper layer of the soil profile or may,
