对陕西某含砷含碳难浸金精矿进行了酸性压力氧化—氰化浸金试验研究,考察了磨矿细度、矿浆浓度、初始硫酸用量、温度、氧化剂用量、氧分压等因素对浸金效果的影响.在适宜条件下,试验获得了理想的技术指标,金氰化浸出率达到97.10%.
Experimental researches on a refractory gold concentrate containing arsenopyrite and carbon from Shaanxi were carried out with the acidic pressure oxidation -cyanide leaching of gold.The influence of grinding fine-ness,pulp density,initial dosage of sulfuric acid,temperature,oxidant dosage and oxygen partial pressure on pressure oxidation-cyanide leaching process was investigated .A good gold recovery (97.10 %) was obtained on proper condi-tions.
