Abstract

Efficient refining of metals in a counter-current reaction launder (CCRL) is contingent upon appropriate gas injection, both to minimize longitudinal mixing (to maintain concentration gradients) and to promote metal-slag mass transfer. Results of physical modeling of a CCRL with bottom injectors are presented, and their implications to a potential industrial design discussed.
