If the copper and cobalt ores are in the oxidized state, copper can be removed by electrolysis in sulfuric acid solution and the cobalt precipitated from the spent electrolyte by adjustment of the acidity of the solution. Cobalt is again eventually obtained in the metallic state by electrolysis.
The cobalt minerals are then floated by using sulphuric acid to decrease the pulp pH to 4. Sodium sulphide is conditioned in the pulp. Cobalt is floated using a combination of xanthate and dithiophosphate and/or MBT. Depending on the cobalt mineralization, use of an activator such as copper
04.05.2019· With 80,000Mt of cobalt reserves, China currently produces cobalt from the Qinghai Deerni copper-zinc-cobalt project owned by Zijin Mining Group in the Qinghai province. The Qinghai Deerni Project, which employs the open-pit mining method, had a ROM production of 1.13Mmtpa in 2018. The Qinghai Deerni mine has been in production since 2007.

Bulk flotation sequence: Under the bulk flotation process, a bulk Cu-Co flotation concentrate is produced at natural pH with xanthate, dithiophosphate and/or MBT, particularly if the copper mineralization is chalcocite. Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages.
From copper and nickel processing. Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy. In nickel smelting, most of the cobalt is recovered during electrolytic refining
16.01.2019· Cobalt was once seen as a by-product of the copper mining process but has seen its demand — and price — skyrocket in recent years due to its critical stabilizing role in lithium-ion batteries. Approximately two-thirds of global cobalt production happens in the Democratic Republic of Congo (DRC), which also has a significant part of global production in copper, as well as tin, tantalum

We expect this to be only the beginning of temporary shutdowns of copper and cobalt mines, and therefore anticipate a serious reduction in copper and cobalt output from the province.

Cobalt mining in Congo. The Democratic Republic of Congo (DRC) alone produces more than 50 per cent of the world’s cobalt and around 20 per cent of it is extracted by hand through a process known as artisanal and small-scale mining (ASM), according to a recent report available on ResearchGate.
Copper sulphide and copper metal (with its inherent cobalt content), because of their higher densities and immiscibility with the slag, settle from the molten slag into the metal bath. Improving recoveries via this mechanism would involve decreasing the viscosity of the slag (by increased temperature or flux additions), and / or increasing the settling time to allow smaller droplets to fall.
