为了检查在无氰化物状态下浮选铜锌矿石的矿浆离子成分,必须同时测定捕收剂、硫化物型硫和硫代硫酸盐离子的浓度。硫化物型硫是铜锌矿石氧化的主要产物之一。在这种情况下,带有电位检查的银量滴定法是最适宜的方法。因为银的阳离子与每一个被测定的离子将形成非常稳固的化合物: 根据化合物溶度积大小,按聂恩斯特(HeHCT)方程计算滴定终点的电位,它们相应地等于:硫化物为
In order to examine the plasma ion composition of flotation points for copper-zinc ores in the absence of cyanide, concentrations of collectors, sulfide-type sulfur and thiosulfate ions must be determined simultaneously. Sulfide-based sulfur is one of the major products of copper-zinc ore oxidation. In this case, the silver titration with potential check is the most suitable method. Because the silver cation and each of the ions to be measured form a very stable compound: The potentials of the end points of the titration are calculated according to the equation of Heterotrime (HECT) based on the magnitude of the solubility product of the compound, which respectively equals:
