为了处理硫化物中难于分解的含金精矿(金呈细粒存在于硫化物中),提出了许多方法,如湿冶方法、火冶方法及这些方法相结合的联合方法。本文列举了按照下列联合流程处理不同成份且难分解的重选、浮选含碳金-银-砷精矿的工艺评价的比较结果:焙砂的氧化焙烧-氰化;压热渣的压热氧化-吸附氰化;细菌 In order to deal with the difficult to decompose gold-bearing concentrate in sulphide, gold present as fine particles in the sulphide, many methods have been proposed, such as the wet-smelting method, the pyrometallurgical method and the combination of these methods. This article lists the results of the process evaluation of flotation of carbon-containing gold-silver-arsenic flotation concentrates for re-election, refractory decomposition of various components according to the following combined process: calcination-cyanidation of calcine; Oxidation - adsorption Cyanide; bacteria
