东坪金矿是产于正长杂岩内接触带的特大型金矿床 ,矿石以富碲、少硫化物为特点[1] 。主要载金矿物为自然金和金、银碲化物。后者包裹于黄铁矿为主的硫化物内 ,属于氰化法的“难溶金”[2 ] ,在表生条件下的氧化产物种类丰富的含金碲酸盐相中含量与自然金相当[3 ,4 ] 。作者用扫
The Dongping gold deposit is an extra large gold deposit produced in the contact zone of the Zhengchang complex. The ore is characterized by rich tellurium and less sulfide [1]. The main gold-bearing minerals are gold and gold, silver telluride. The latter is encapsulated in pyrite-based sulfides and belongs to the “insoluble gold” of cyanidation [2]. The abundance of oxidized products of tellurite in the epiphytic conditions is similar to that of natural gold Quite a few [3, 4]. Author with sweep
