Official data from the Ministry of Mines and Minerals Development shows that Zambia's annual cobalt production in 2022 has reached 251 tons, representing a 2% increase from the 247 tons produced in 2021.
The core production area is the Zambia-Congo (DRC) copper-cobalt mineral belt in Central Africa. The main cobalt-containing minerals are pyro-cobaltite and pyro-cobaltite. ... Ore Processing. After mining, the ore needs to be processed to extract the cobalt and other valuable metals within it.
It is also unique as it is the only operation in the world which produces both LME registered cobalt and copper metal. Chambishi Metals operations include treatment of cobalt/copper sulphide/oxide concentrates, and cobalt carbonate/hydroxide materials. The facility has a nominal capacity of 6.8ktpa of cobalt metal and 55ktpa of copper metal.
The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical characteristic, the liberation …

The president of the zambia Chamber of mines reported that
Refining locally would also decrease the emissions of products destined for the European market by bypassing the step of shipping minerals to China for processing. Though the DRC's soil contains approximately 80 percent of the world's cobalt, the country only holds three percent of the battery and EV value chain.
For example, excessive acid leaching of the cobalt ore, followed by biphasic solvent extraction, chemical precipitation, and electrowinning, has been the typical processing route for leaching ...
