Cobalt extraction - Wikipedia
Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel. They depend on the concentration of cobalt and the exact composition of the used ore.
Ores Containing Cobalt | Cobalt Institute
Ores Containing Cobalt. Mineralogy . A wide range of minerals contain cobalt although many are rare or unique to individual localities. There are approximately 30 principal cobalt-bearing minerals and over 100 more which contain minor amounts of the metal or include cobalt as a substitute for other elements. Cobalt may substitute for transition metals in many minerals and stone compounds ...
Copper-Cobalt ores
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. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and combinations of fatty acid to recover the cobalt minerals ...
Cobalt - an overview | ScienceDirect Topics
Cobalt –copper sulfide ores are being exploited in several Democratic Republic of Congo and Zambia mines (Katanga, 2010). Cobalt and copper are extracted in the following steps: (a) flotation; (b) sulfation roasting; (c) leaching (sometimes along with additional oxide concentrate or ore); (d) solvent extraction separation of copper from ...
cobalt processing | Uses, Supply, & Facts | Britannica
In the copper-cobalt ore bodies of central Africa and Russia, cobalt occurs as sulfides (carrollite, linnaeite, or siegenite), the oxide minerals heterogenite (hydrated cobalt oxide) and asbolite (a mixture of manganese and cobalt oxides), and the carbonate sphaerocobaltite. In the copper-nickel-iron sulfide mines of Canada, Australia, Russia, and other regions, cobalt is present in place of ...
Cobalt Metal Characteristics - ThoughtCo
Cobalt naturally occurs in nickel-bearing laterites and nickel-copper sulfide deposits and, thus, is most often extracted as a by-product of nickel and copper. According to the Cobalt Development Institute, about 48% of cobalt production originates from nickel ores, 37% from copper ores and 15% from primary cobalt production.
Worlds Biggest Cobalt Producers - The Balance
Ore is transported via the Port of Townsville to the refinery by rail where cobalt is refined and sold as purified feedstock to cobalt stone manufacturers. Russia Norilsk Nickel in Russia is the world’s largest producer of nickel and palladium and one of the largest producers of cobalt, platinum, and copper.

Cobalt—Styles of Deposits and the Search for Primary Deposits
Cobalt—Styles of Deposits and the Search for Primary Deposits. Murray W. Hitzman, Arthur A. Bookstrom, John F. Slack, and Michael L. Zientek. Abstract. Cobalt (Co) is a potentially critical mineral. The vast majority of cobalt is a byproduct of copper and (or) nickel production. Cobalt is increasingly used in magnets and rechargeable batteries. More than 50 percent of primary cobalt ...
Where to Find Copper, Nickel, and Cobalt …
The ore also carries about 1.5 per cent copper as copper pyrites. In addition to nickel and copper, these ores carry small values in gold, silver, and metals of the platinum family. The ore bodies are found at or near the contact of a great norite mass with granite, etc. The prospector’s guide has been the gossan, or iron cap, left by the easily weathered minerals. Attempts have been made to ...

Sulphating roasting of copper-cobalt - SAIMM
Sulphating roasting of copper-cobalt concentrates by J. Güntner* and J. Hammerschmidt* Synopsis Most copper/cobalt ores from the Central African Copperbelt contain sulphidic compounds, which are not extractable in direct leaching. Roasting provides the possibility to transfer the valuable components into leachable compounds. In an operation window defined by temperature and off-gas ...
