Bauxite Beneficiation: Efficient Way to Remove Silica in Bauxite

The bauxite is usually dried or calcined before magnetic separation because the heating converts siderite (FeCO 3) to magnetite (Fe 3 O 4), leaves pyrite (FeS 2) as a magnetic residue, and makes hematite (Fe 2 O 3) and other magnetic minerals strongly magnetic. Then use a magnetic separator to separate the magnetic material.
