Chilean miner SQM said the coronavirus outbreak had yet to hit its lithium output, but warned it might have to scale back plans for 2020 if a slump continues in demand for the coveted battery metal. The world’s No. 2 miner of lithium had planned to unleash at least $330 million in 2020 to expand production capacity out of Chile’s Atacama salt flat, according to SQM board chairman Alberto Salas.
