  Concentration of bauxite fines via froth flotation - Brasil

  The iron and titanium minerals present in the ore follow the bauxite. Therefore, the depressed product must be separated by magnetic separation to yield a bauxite concentrate and a magnetic product. 1.1 Literature review and history. In the Zona da Mata region, there are two kinds of bauxite ore, depending on the mother rock: gnaissic and ...
