What Are The Factors Affecting Gold Leaching?

Gold is not active metals, in the process of cyanide leaching, gold can be under the action of oxygen and cyanide complexation reaction (CN), produce a watersoluble melamine aurous acid salt complex [Au (CN) 2], so the cyanide agent is a key factor determine gold dissolved, in general, to ensure that a certain amount of free cyanide in the

4 Reasons and Solutions of Poor Gold Leaching Effect

Some gold ores have active organic carbon or graphite, etc. Because the carbon contained in the ore has considerable activity, the phenomenon of "carbonaceous gold robbing" will occur during the leaching process. They will adsorb the dissolved gold and then precipitate it again, thereby reducing the gold leaching rate. Solution

Gold Metallurgy and Leaching Process

2020107&ensp·&enspLeaching, 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
