摘要
对黄铁矿型难浸金精矿采用臭氧氧化预处理,在选定的氧化工艺条件下,可有效地分解载金黄铁矿,浸出铁和硫。试验主要考察了通气量、反应时间和温度、矿浆浓度、FeCl3.6H2O用量等因素对臭氧氧化预处理过程的影响,并确定了最佳反应条件。
Oxidation pretreatment through ozone is made to pyrite--like difficult leachable gold ore concentrate. Under the set technological oxidation conditions, the gold--bearing pyrite is easily decomposed thus Fe and S are leached out. Test is done to survey the effect of airflow, reaction duration ＆ temperature, slurry density and FeCl2 6H2O addition on oxidation pretreatment process thus to determine the best conditions for pretreatment.
