Flotation of oxidized copper and cobalt haut katanga

Mar 31, 2021 The present research aims at minimizing the pollution of watercourses by industrial discharges. It is interested in the biological treatment of clarified wastewater from the flotation of copper (Cu) and cobalt (Co) oxidized ores conducted in the region of Katanga (Bwapwa 2019; Shengo and Mutiti 2016). It specifically focuses on the design of a treatment scheme and on evaluating its

    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

    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

    Nov 01, 2019 Sulphidisation followed by flotation is the preferred beneficiation technique for oxidised copper-cobalt ores. • The integration of CPS systems into the flotation circuits can help minimise reagent overconsumption. • Application of selective flotation can help a concentrator to produce separate oxide and sulphide concentrates

    The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – e.g. the Kolwezi Tailings Project

    Jul 26, 2016 The deposit of Luiswishi is listed among the most important copper deposits mined in Katanga. Its reserves of copper and cobalt are estimated at 7.5–8 million tons present mainly in the form of oxide minerals rich in talc and hosted in the clayey and dolomite sediments including bornite, carollite and heterogenite (Coakley 2001; NCK 2008)
