A study of reduction and magnetic separation of iron from

The removal of iron as magnetite from a high iron bauxite ore was investigated by carbothermal reduction and magnetic separation. Thermodynamic calculations using HSC Chemistry 6·1 were utilised to determine the equilibrium compositions of the reaction products as a function of temperature and carbon additions.

A process for enhanced removal of iron from bauxite ores

Jun 01, 1991· 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.

Semi-Smelting Reduction and Magnetic Separation for the

This work presents a semi-smelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore. The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized. The results show that the iron nuggets and alumina slag can be

Technical Note Removal of limestone from bauxite by

Bauxite is the main source for the production of alumina and metal aluminum by the Bayer process. Limestone is an impurity associated to bauxite due to geological and morphological conditions prevailing during its formation. Experimental work has shown that limestone can be easily removed from bauxite using magnetic separation techniques.

Iron Recovery from Bauxite Residue Through Reductive

Jun 20, 2018· The scope of this work is to develop and optimize a reductive roasting process followed by wet magnetic separation for iron recovery from bauxite residue (BR). The aim of the roasting process is the transformation of the nonmagnetic iron phases found in BR (namely hematite and goethite), to magnetic ones such as magnetite, wüstite, and metallic iron.

EXTRACTION BR 2018 Conference Red Mud Bauxite

Jun 28, 2018· The samples generated under the optimized conditions were subjected to magnetic separation in a dry and wet magnetic separator. The objective of the experiments was to separate the magnetite from the non-magnetic fractions of the reduced sample. Dry and wet magnetic separation were carried out in a Frantz and Davis tube separator respectively.

Recovery of iron from bauxite residue using advanced

Apr 01, 2019· Reduction roasting followed by wet magnetic separation of red mud from Greek alumina plant is done for the extraction of iron. It is found that reductive roasting of calcined red mud at 500 °C and then wet magnetic separation gave a product with 36% iron content (Li et al., 2009). A major amount of work is done in China.
