    4 reasons and solutionsof poor gold leaching effect

    In the cyanidation process, they are easily oxidized and decomposed to produce sulfuric acid, ferrous sulfate, ferric subsulfate, ferric thiosulfate, etc. The decomposed substance reacts with cyanide or alkali, so that a large amount of oxides, cyanide and alkali are dissolved before gold dissolves, thereby hindering gold leaching. Solution

    Metallurgical ContentLearn CyanidationDevelopments in the Carbon-In-Pulp ProcessDesign Criteria Commercial Operations 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

    Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes
