| Abstract: | Taking the Carlin-type gold deposits in southwestern Guizhou and northwestern Guangxi for example, this paper discusses the difference in existing state of gold for primary ore and oxidized ore in this type of gold deposits, and makes an analysis of the existing principle on the basis of crystal chemistry and geochemistry theories. This paper also makes an especial approach to the chemical model of clay minerals' exogenic hydrothermal solution action in the two types of ores.The results provide new thinkings for the technological process of chemical ore dressing of primary ores. |
