REUTERS/Chris HelgrenTORONTO, March 21 (Reuters) - Investors have yet to embrace Canadian miner Teck Resources Ltd's (TECKb.TO) proposal to spin off its highly polluting coal business and focus on production of copper to help supply society's move toward electric vehicles. Last month, Teck announced a split into copper-focused Teck Metals and Elk Valley Resources (EVR), which will focus on high-margin coal for steel making. In 2021, South African miner Anglo American demerged and listed its thermal coal business. "The coal business is profitable for now, and using its proceeds to fund its copper business is a pragmatic way towards transition," said Dustyn Lanz, Senior Advisor ESG Global Advisors.
