Cobalt beneficiation process

Aug 24, 2021

Nov 01, 2019 Gravity separation is used either as a preconcentration step or during the extraction of rich concentrates from process tails. • 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

    A procedure was developed for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydro-metallurgical process. The procedure consists of (1) oxygen pressure leaching; (2) iron, arsenic, and copper removal from the leach solution by precipitation; (3) selective extraction of cobalt and zinc from solution; (4) electro-deposition of the cobalt
