    Leaching. Leaching is the fundamental method in hydrometallurgy for recovering metals from ores. The process involves dissolving the metals into a solution and then separating the solution from the insoluble waste. Dissolution can be done by a number of chemicals including dilute cyanide, dilute sulfuric acid or other reagents
