Manganese and zinc solvent extraction process

The process of the present invention relates to the recovery of manganese and zinc ions from aqueous sources by liquid-liquid solvent extraction. More particularly it is concerned with a method for increasing the relative concentration of desired metal ions with respect to impurities in electrowinning feed solutions.

Recovery of zinc and manganese from spent alkaline

2003-4-10  The extraction of zinc and manganese by Cyanex 272 from sulphate solution as a function of the equilibrium pH at 50 °C is shown in Fig. 1. It was observed that negligible manganese co-extraction took place at pH < 2, so zinc can be extracted from the mixed electrolyte solution with little or no manganese contamination.
