flotation of oxidized copper and cobalt haut katanga

Dec 10, 2016 Unfortunately, the recycling of process wastewater is not a widespread practice at copper ores concentrators operated in Haut-Katanga, which is a mining region confronted since many decades to water pollution related to the mismanagement of flotation effluents (Chadwik, 2008, Kanku, 2007, Kitenge, 2008). The present research work is interested in the locked-cycle recycling of process water during flotation of copper-cobalt oxide ores from the Luiswishi deposit located in Haut-Katanga

    the copper and cobalt have been recovered with a concentration ratio of 3.5 (9). In this study, we attempted flotation of oxidized copper ore. When this was unsuccessful, we used a sulfurization process developed in our previous studies. As a result of this process a new surface forms on the oxidized copper particles and flotation
