INCREASE OF EFFECTIVENESS OF THE ELECTROFLOTATION PROCESS OF RECOVERY OF A DISPERSED PHASE OF NONFERROUS METALS FROM WATERY SOLUTION

А method is suggested and studied of removing nonferrous metals of from waste waters. The method is, that waste water containing nonferrous metals is treated to adjust pH to 9-10, after which sodium orthophosphate solution is added at metal/phosphate ion weight ratio 1:(0,5-0,7) resulting in formation of slightly water-soluble metal hydroxyphosphate whose solubility is inferior to that of corresponding metal hydroxide.
