ways of producing bauxite

ways of producing bauxite - bovis-zaventem.be

Mar 11, 2019 A lime sintering process for production of alumina from boehmite and diaspore bauxites was developed for producing alumina from low grade bauxite in China and Russia. The process involves a pyro-metallurgical sinter approach, which produces aluminum while "locking up" the silica as clinker, thus preventing it from contaminating the alumina.
