摘要
The invention relates to the mining industry, in particular to geotechnological solutions used in underground and heap leaching. The goal is to increase the leaching efficiency by reducing the accumulation of ballast impurities and the consumption of sodium hypochlorite. Additional sodium carbonate is added to the leaching solution, including sodium hypochlorite, sodium chloride and water, in the following ratio of components, g / l: sodium hypochlorite 0.5-1.5; sodium chloride 200-300; sodium carbonate 5-60; water the rest. When sodium carbonate is introduced into the leach solution, the initially formed carbonate complexes of some metals with an excess of sodium chloride are converted into a solution in chloride. Thus, sodium carbonate is not consumed, but acts as a catalyst for the process. 1 tabl C
