氯化法处理难溶金矿应用于许多低品位金冶炼工艺中。实际应用中,此法可以氧化硫化矿、钝化散布的有机碳。但是,在用氰化物浸取前,需要对氯进行中和。美国矿务局的研究拓展了现有的氯化技术,使得金的回收无需再使用氰化物,还使得一些目前认为无法采用氯化法或氯化/氰化法进行处理的矿石能得以处理。两种碳质矿石的无炭氯化处理仅能提取1％到20％的金,而加炭氯化法(CICL)处理能使回收率达到90％,而且以金属态吸附于炭上,实验统计表明,氯从炭载体上洗脱金属态金的洗脱率可超过90％。
Chloride treatment of insoluble gold used in many low-grade gold smelting process. In practice, this method can oxidize sulphide ore and passivate scattered organic carbon. However, it is necessary to neutralize the chlorine before leaching with cyanide. Research by the US Bureau of Mines has expanded the existing chlorination technology to eliminate the need to reuse cyanide for gold recovery and to enable some currently considered incalculable chlorination or chlorination / cyanidation processes. Carbonless chlorination of two types of carbonaceous minerals can only extract 1% to 20% gold, while CICL treatment can achieve a recovery of 90%, and the metal is adsorbed on the carbon in the experiment The statistics show that the elution rate of the metal from the metal carrier eluted by chlorine can exceed 90%.
