Recovery of nickel from hydrate pulps at amino carboxylic cationites

Abstract

Regularities of the sorption of nickel from hydrate pulps using amino carboxylic cationites ANKB-35, S 930, and TP 207 are investigated. Kinetic curves and sorption isotherms for these cationites are constructed. It is revealed that it is reasonable to absorb nickel from pulps at pH = 4-5. The desorption of nickel from cationites is investigated. It is shown that cationite TP 207 possesses the maximal sorption capacity. © 2013 Allerton Press, Inc.
