Cobalt is widely scattered in the earth’s crust and is found in a variety of different ores in several countries. Cobalt is only extracted alone from the Moroccan and some Canadian arsenide ores. It is normally associated as a by-product of copper or nickel mining operations. Around 55% of the world cobalt production comes from nickel ores.
Sep 01, 2020· Introduction. The African Copperbelt, or colloquially “the Copperbelt”, is the largest sediment-host copper province in the world. It is estimated that the Copperbelt contains 5 billion tonnes of ore containing 3.3% copper, yielding 185 million tonnes of copper.
We are one of the world’s leading producers of cobalt a metal in rising demand thanks to its use in batteries for electric vehicles and portable electronics. We produce cobalt mainly as a by-product of copper mining in the Democratic Republic of Congo (DRC), but also as a by-product of nickel mining in Australia and Canada.
Nearly all cobalt is found associated with ores of copper, nickel, or copper-nickel. 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,

In the DRC, ERGA mines cobalt and copper, processing the ore at Boss Mining, Frontier Mine and Comide. We have a number of development projects and near-production assets in the DRC including Metalkol RTR, which is a comprehensive hydro-metallurgical facility. Chambishi Metals, located in Zambia, is ERGA's central cobalt and copper refinery.
The Kolwezite or copper Cobalt carbonate hydroxide[ (Cu, Co)2CO 3 (OH) 2] is a rare mineral similar to malachite. This ore contains a large percentage of cobalt instead of part of copper in malachite. For copper cathode production, oxidized or sulfurous copper ore can be used. It is simply the mining processes that will vary.
Most cobalt is produced as a byproduct (of copper or nickel mining), which limits the flexibility of producers to respond to changes in market demand and results in periods of oversupply or shortage.
Production and Supply; Ores Containing Cobalt. Cobalt is almost always a by- or co-product of mining for other base metals, chiefly nickel and copper. Large quantities of cobalt also occur on the sea floor, contained within manganese nodules and cobalt-rich crusts, although they are not economically viable with current technology and
Tolling production requires demanding know-how and skills. The choice of stakeholders (mining, transporters, processing unit and storage) for example, has a direct impact on the quality and direct costs of high-grade copper concentrate production, copper cathode production or cobalt or copper cathode and blister production. Therefore, a good knowledge of extractive metallurgy and metallurgical

The production of cobalt hydroxide is made on the basis of copper-cobalt ores. This represents 80% of cobalt hydroxide production in the DRC. The remaining 20% comes from artisanal cobalt mines.
Recovery from copper-cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble sulfates and iron into insoluble hematite.The calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyte.Oxide concentrates are introduced at this leaching step to maintain the acid balance
