Warranty: 1 Year
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 pyrometallurgical sinter approach which produces aluminum while ”locking up” the silica as clinker thus preventing it from contaminating the alumina
