Century Aluminum-Brimstone MoU and the alumina supply chain

Century Aluminum signed a memorandum of understanding with Brimstone under which the companies would work toward supplying domestically produced alumina from Brimstone’s planned commercial-scale facilities to Century’s US smelters, the companies said.

The non-binding agreement, announced last week, outlines a potential future supply relationship rather than a purchase contract. Brimstone has not yet commercialized its alumina production process, which would produce smelter-grade alumina from calcium-bearing silicate rock instead of imported bauxite.
