29/02/2016· If the solution is rich enough can be treated by zinc powder and the precipitated obtained obtained will be sent to retorting and smelting. For gold extraction the strength of cyanide solution ranges from 0.01 to 0.05%. Lime is added to the process in order to have a pH near to 10 11.
24/06/2015· Gold Metallurgy and Leaching Process. 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 from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, ...
gold complexes in aqueous solutions, and this is a far broader subject. It has been traditionally accepted that gold complexes in aqueous solution can exist in one of two oxidation states, the aurous or the auric , and that all the gold complexes of hydrometallurgical interest fall into these two groups.
