摘要
本文用氧化亚铁硫杆菌（Ｔｈｉｏｂａｃｉｌｕｓｆｅｒｒｏｏｘｉｄａｎｓ）对含砷金精矿进行了氧化预处理脱砷实验，脱砷率达９８％。生物浸渣用ＳＯ２－硫脲浸取体系浸出金，不仅降低了硫脲用量，而且缩短了浸出时间，金的浸出率达９５％以上。该工艺具有广阔的应用前景。
An experimental study on bacterial preoxidation of the refractory gold concentrate containing high concentration of arsenic and sulphur and recovering gold by thiourea was presented in this paper.The oxidation rate of arsenic is about 98%.The gold leaching rate by the system of sulphur dioxide thiourea is more than 95%.This process appears feasible for the consumption of leaching reagent is decreased and for the time of gold lesching is shortened.
