摘要
紫木的原生金矿为还原型金矿。用溴－溴化纳溶液浸泡１５～２０天，可浸出其中９０％左右的金。若用氯气使溴再生，处理一吨矿要消耗约８９ｋｇ氯气。浸出率高低与矿石中硫氧化多少有密切关系。
Zimudang Primary gold ore is called reducing type gold ore.About 90% gold can be leached out using solution of bromine and sodium bromide to macerate the ore for 15￣20 days.ln case bromine is regenerated by chlorine, only 89 kg/t chlorine is consumed. Gold extraction rate relates to oxidation level of sulfide in ore.
