The concern originates form Brazil, where mainly Mineração Rio do Norte (MRN), Mineração Paragominas, Alcoa and Companhia Brasileira de Alumínio (CBA) produce bauxite, the raw material for alumina.
A new resolution issued by the Brazilian mining agency ANM on February 15 banned any upstream tailings dams in the country
. Current structures should be decommissioned by 2023, it said.
The ban has been under public consultation for amendments until Friday March 15. According to a source with knowledge of the discussions, the aluminium industry fears a much stricter timeframe than the one hinted earlier could be proposed.
“Not only bauxite producers, but all of the Brazilian mining through Ibram [Brazilian Mining Institute, the association representing miners] expressed their discontent of that possibility,” the source told Fastmarkets.
