A little-known cobalt miner in the Democratic Republic of Congo plans to ramp up output so fast it will soon be out-produced only by industry leader Glencore Plc.
Chemaf Sarl, a closely held Lubumbashi-based company, and several other firms are capitalizing on a boom in demand that’s transforming small copper miners into major cobalt players, as refiners and automakers scramble to secure long-term supplies.
Prices for the metal, used to make rechargeable batteries in electric vehicles, have more than tripled in the past two years. New output from Congo means the supply of cobalt could exceed demand for a few years, as it did narrowly in 2017, Guildford, U.K.-based metals trader Darton Commodities Ltd. said in a February report.
