Acid Leaching Copper Flotation Concentrate

The bulk of the slurry was clarified by a four-stage countercurrent decantation (CCD) and wash treatment, using 0.1 lb/st of the nonionic flocculant, to produce a supernate with minimum dilution while recovering greater than 99 pct of the soluble Cu present. This clarified pregnant leach liquor had a density of 1.09 g/mL and a pH of 0.8.
