a process to remove iron from bauxite ore is described in which the ore is first finely crushed, calcined, and contacted with a reducing gas to convert iron present as very weakly magnetic goethite or hematite to magnetite or elemental iron. the ore is then passed through a magnetic separator to remove the iron.
the iron oxide in the bauxite ore was reduced to magnetite and/or iron and the magnetic frac- tion was separated using a davis tube tester. three exper-.
calcium oxide, cao, is also present, to a lesser or greater degree, in the form of calcite, caco3, the main constituent of limestone. this particular mineral is not a

the ore is firstly reduced in co and h2 atmosphere to convert iron contamination of bauxite to magnetite or elemental iron. then material is finely crushed and
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
