| Abstract: | Gold deposition mechanism is the key to understanding the mineralization mechanism of hydrothermal deposits. In this paper, recent development in the study of the deposition mechanism of Au from hydrothermal solution is summarized, the mechanism controlled by solubilities of main Au-bearing complexes is introduced, and such mineral surface effects as adsorption, reduction and electrochemical accumulation are elaborated, and their influence on gold deposition is discussed as well. |
