Diversified miner Rio Tinto’s Canadian aluminium operations have been extended with the Aluminium Stewardship Initiative’s (ASI) Chain of Custody certification, reinforcing the miner’s commitment to responsible mining and metals production.
The certification provides independent verification that material can be traced through a ‘chain of custody’ spanning Rio’s Gove bauxite mine in Australia to its alumina refinery, aluminium smelters and casthouses in Quebec and British Columbia, Canada.
