Recovery of cobalt and copper through reprocessing

2013-12-1  The present research aims at recovering copper and cobalt through reprocessing of tailings from flotation of oxidised ores of copper and cobalt achieved at the Kambove Concentrator (DRC). It focuses on the determination of the reagents’ dosage that enables obtaining the highest recovery of copper (44.80%) and cobalt (88.30%) through flotation
