2009-3-1  Bauxite flotation practice Worldwide, the industrial practice for bauxite consists in feeding the ROM ore directly to the alumina production plant. Shaffer (1985) , in his contribution to SME Mineral Processing Handbook chapter on alumina, literally writes that “the intrincate milling and mineral dressing techniques common in the base metal industry are not used on bauxite”.
