Projections are that a typical 50,000 ton-per-year copper electrowinning plant would see a payback in 18 months. One of the persistent and costly challenges associated with the SX/EW process for copper recovery is the build up of iron (Fe +3). Iron is leached along with copper from the ore and accumulates in the electrolyte circuit as …

1. Introduction. The ever increasing global demand of metals has led to quick expansion of mining and metallurgical industry operations, resulting in higher risk for environmental pollution by the acidic process and wastewaters of said industries (Simate and Ndlovu, 2014).The permissible limit for copper in water is ca. 0.1–4 ppm due to its …
