摘　　要：金的沉淀机理是了解热液金矿床成矿机制的关键。本文总结了金从热液中沉淀机理的最新研究成果，介绍了各种主要含金配合物的溶解度拨制机制，阐述了矿物表面吸附／还原以及电化学富集等矿物表面作用对金沉淀行为的制约。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.
