A process for producing alumina from bauxite is described in which bauxite is treated with an alkali to form a mixture comprising a solution of aluminum-containing ions and alumina trihydrate is precipitated from the solution. The process comprises treatment of the solution before or after the precipitation step with a layered double hydroxide in order to remove impurities from the …

A technique has been proposed for recovering iron from hematite-rich diasporic-type bauxite ore in this study. Direct reduction roasting followed by low intensity wet magnetic separation process was carried out. The parameters including reduction temperature and time, sodium salts, grinding conditions and magnetic field intensity for separation of iron were determined. The …

Magnetic separation Magnetic separation of the specimens of ore which had been both calcined and reduced resulted in the production of a non-magnetic bauxite product containing less than 2.0% iron (as Fe203). Table II summarizes test condi- tions and results. It can be seen that no iron could be removed from the raw bauxite in the Davis tube.
