Cobalt mining is concentrated in large scale copper and nickel mines across the world, while processing is concentrated in China. With the sharp increase in demand, driven by a drive to reduce transport emissions, the global supply chain is evolving fast, with new mining operations starting up or expanding in many parts of the world.
The Gibraltar mine was originally built in 1972 and designed to process 36,000 tonnes of ore per day. Taseko Mines came along and purchased the site in 1999, and in 2004 it gave the project a $700 million restart, realizing its vast potential for increased copper production.

The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation roasting–sulfate decomposition …

Cobalt is extracted as a byproduct from copper and nickel mining. [4] Copper-cobalt oxide and sulfides go through several processes to ultimately end with pure cobalt or other cobalt compositions. [4] In the Congo, cobalt is found in …
Over 30 magmatic Ni-Cu-Co sulfide deposits have been discovered in China (Fig. 1), two of which are the world-class Jinchuan deposit and the super-large Xiarihamu deposit, with nickel metal resources exceeding one million tonnes representing ∼80% of China's nickel and cobalt resources [21].China's earliest discovered magmatic Ni-Cu-Co mineralisation is the …
The McIlvenna Bay copper-zinc-gold-silver project has a projected 18-year mine life, over which it could produce 65 million lb. of copper-equivalent annually, according to the company's 2022 ...
Cobalt mining stands as a pivotal industry in the modern world, fueling the production of batteries, electronics, and various other industrial applications. Despite its significance, cobalt extraction presents numerous environmental, social, and ethical challenges that necessitate a careful approach. ... The mining process varies depending on ...

The flotation concentrate was then subjected to bioleaching by acidophilicbacterial strain, Acidithiobacillus ferrooxidans, for the treatment of base metals such as cobalt, nickel and copper. The application of bio-collector reduced the silica and alumina-based impurities, which aided the bio-leaching process to achieve a Cu recovery of about 74%.
Copper and cobalt circuits Copper and cobalt are usually simultaneously dissolved from the oxide ores using acid and SO 2 (added as sodium metabisulphite, SMBS) for reduction of Co(III) …

Cobalt is mined across the world and the vast majority is produced as a by-product from large scale copper and nickel mines. The process of cobalt mining involves many steps, including locating suitable deposits and extracting the ore before refining it into a usable form. Cobalt is only extracted alone in Morocco and some Canadian arsenide ores.
Chinese refining activity reached 140,000 tonnes in 2022, giving the country a 77% global share of refining capacity. The price of the metal hit a 32-month low this month amid a surge in production.
Cobalt Life Cycle. The global cobalt value chain is composed of a range of different actors. Cobalt mining is concentrated in large scale copper and nickel mines across the world, while processing is concentrated in China.
Cobalt production in the Copperbelt increased about 600% between 1990 and 2021, according to data from the U.S. Bureau of Mines and the U.S. Geological Survey. The vast majority of cobalt is produced as a byproduct of copper mining, though some copper mines do not produce any cobalt.

Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a "speiss", rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.
Chelating resins can be used to recover important metals from different sources, and it is important to understand which resin is most suitable for each metal [1]. This review benefits the mining industry because chelating resins can be used to recover metals from low-grade ores and mining tailings, increasing the industrial process efficiency [2–4]. Furthermore, the use of …
