摘要： A process of extracting copper from copper sulphide minerals which is enhanced at solution potentials exceeding 700 mV SHE, in the absence of any microorganism, by contacting the minerals in a pre-treatment phase using an acid solution at a high chloride content containing dissolved copper.
摘要翻译： 在没有任何微生物的情况下，通过使用含有溶解铜的高氯化物含量的酸溶液在预处理阶段接触矿物质，在硫酸铜矿物中提取铜的过程在溶液电位超过700mV SHE时增强。
