Chile’s Codelco, the world’s largest copper miner, said on Wednesday it would temporarily suspend construction on some projects in a bid to halt the spread of coronavirus, as the company´s unions ratcheted up pressure for more safety measures. In a statement Codelco said the 15-day suspension applied to remaining work being carried out to make Chuquicamata an underground mine, and projects at an early stage at Rajo Inca and Traspaso Andina.
