在采用联合法选别氧化和混合铜矿石时,沉淀铜的浮选是在矿浆液相中含有高浓度盐类的酸性介质中进行的。某些离子的存在,进入第一段作业的氧化剂(Cu~(2+)、Fe~(3+))和氯的离子,在使用大多数相应的捕收剂时都会造成铜和铜矿物可浮性的降低,并使技术指标变坏。甚至象水溶性丁基黑药(TΦБ)这样有效的药 Flotation of precipitated copper is carried out in an acidic medium containing high concentrations of salts in the slurry liquid phase when the combined method is used for the selective oxidation and mixing of copper ores. The presence of some ions, the oxidants (Cu2 +, Fe3 +) and chlorine ions entering the first stage of operation, result in copper and copper minerals when most of the corresponding collectors are used Reduced floatability and worsened specifications. Even effective drugs like water-soluble butyl black drug (TΦБ)
