铜矿石中金银赋存状态的研究

MODE OF OCCURRENCE OF GOLD AND SILVER IN COPPER ORES

Gold-bearing base-metal deposit is one of the important types for gold and has received increasing attention. Results of this study show that all the gold in these ores occur us fine-grained minerals and except for tctrahedrite in which silver occurs mainly as solid solution component, silver minerals can account for most of the silver content in other ere minerals. Our study also indicates a close relationship between gold and copper, arsenic; and between silver lead and zinc. Additionally, it is noticed that the precipitation of gold is earlier than silver.
