根据试验结果制定出了在温度不高(40～60℃)的硫酸溶液中同时用臭氧和过氧化氢(这个反应称为Peroxone反应)形成的氧化剂和硫酸铁浸出硫化矿精矿和中矿的工艺。采用多种氧化剂可以使浸出中臭氧的用量降低一半。随着选矿产品的矿物组成和所用的活化方法的不同,浸出时间一般在3～10h之间波动。浸出前对精矿进行机械活化处理可以提高金属浸出率。
According to the test results, the oxidant formed by ozone and hydrogen peroxide (this reaction is called Peroxone reaction) in the sulfuric acid solution with low temperature (40 ~ 60 ℃) and the sulphate leaching sulfide ore concentrate and medium ore Process. The use of multiple oxidants can reduce the amount of ozone used in leaching. With the mineral composition of mineral processing products and the activation of the different methods used, the leaching time is generally between 3 ~ 10h fluctuations. Leaching before the mechanical activation of the concentrate can improve the metal leaching rate.
