Dry beneficiation of bauxite minerals for greater yields

Dry beneficiation of bauxite minerals for greater yields. The primary starting material for aluminum refining is bauxite. Since aluminum is a reactive element and does not occur naturally, aluminum-rich ore needs to be refined to produce alumina and aluminum, resulting in a significant generation of by-product residue.
