A visitor walks past a brine lake at a Sociedad Química y Minera de Chile (SQM) lithium mine on the Atacama salt flat in the Atacama Desert, Chile, on Wednesday, May 29, 2019. Almost three-quarters of the world’s lithium raw materials come from mines in Australia or briny lakes in Chile, giving them leverage with customers scrambling to tie-up supplies. The mining nations hope to bring refining and manufacturing plants that could help kickstart domestic technology industries. Photographer: Cristobal Olivares/Bloomberg
