Brimstone and Century Aluminum to Create First US Aluminum Mine-to-Metal Supply Chain

Aluminum is needed for national defense and electric vehicles, but the U.S. produces less than one-sixth of the aluminum it consumes, Brimstone said.

San Francisco-based Brimstone and Chicago-based Century Aluminum signed an agreement June 25 to create the first U.S. mine-to-metal supply chain to produce aluminum.

The memorandum of understanding sets out a plan for Brimstone to supply Century Aluminum—the largest American primary aluminum producer—with significant volumes of alumina, the key ingredient in aluminum production, from a plant the company is building in Reno, Nevada.
