Description

technical field [0001] The invention relates to an intelligent on-line real-time monitoring system and method for metal ion concentration in the colloidization process of manganese-zinc aging liquid, and belongs to the field of devices and methods in the electrolytic solution preparation section of the hydrometallurgical industry. Background technique [0002] The electrolytic metal manganese and zinc are both electrolyzed by sulfate aqueous solution. Since zinc ore and manganese ore are accompanied by impurities such as calcium, magnesium, iron, copper, cobalt, nickel, germanium, and lead to varying degrees, Zn +2 and Mn +2 It is a highly electronegative metal (-0.762v, -1.18v). The important condition for electrolysis is that the sulfate solution should not contain other competing metal ions as much as possible, so the zinc sulfate and manganese solutions must be fully purified before electrolysis. [0003] At present, zinc and manganese enterprises need to age the purif...
