Title

EXTRACTION OF ZN, MN AND CO FROM ZN-MN-CO-CD-NI CONTAINING SOLUTION USING D2EHPA, CYANEX® 272 AND CYANEX® 302

Abstract

 Effects of pH, D2EHPA, CyanexÒ 272 and CyanexÒ 302 on extraction of zinc, manganese and CObalt from a ZN-Mn-Co-Cd-Ni COntaining solution at the room temperature was COmprehensively investigated. Addition of CyanexÒ 302 indicated a left-shifting-effect on the extraction curve of zinc, a right-shifting-effect on the extraction curve of manganese and no effect on the extraction of CObalt. Addition of CyanexÒ 272 shifted all three curves to the right. Therefore, the most suitable extractant for separation of zinc from manganese was therefore 0.3-0.3 mixture of D2EHPA and CyanexÒ 302, and that for separation of manganese from CObalt was pure D2EHPA.The stoichiometric COefficient for the extraction reaction of zinc (whether using pure D2EHPA or a mixture made of D2EHPA with CyanexÒ 272 or CyanexÒ 302) was 3. It varied from 4 to 5 for manganese, when the quantity of CyanexÒ 302 dissolved in D2EHPA increased from 0 to 100%.Utilizing the above results, a two stage leaching was devised to recover zinc, manganese and CObalt from a COmplex solution. At the first stage, a 0.6M D2EHPA extractant COuld recover zinc, and a scrubbing reaction with organic: aqueous (O: A) ratio of 20: 1 COuld wash-out cadmium from the raffinate. In the second stage, the extracting residue was treated with 0.6M D2EHPA for recovery of manganese. This stage was then followed by a one-stage scrubbing of CObalt with O: A ratio of 20: 1.
