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 Al 2 O 3 content of the alumina slag was investigated and optimized.
Dry Magnetic Cobbing Separation. Cobbing, as used in this paper, refers to coarse dry magnetics separation. It is applicable when, by its practice, plant cost can be reduced or the value of its products increased by the removal of a barren or lean reject or a high grade final product. This paper attempts to describe cobbing as it is ….
· Here''s an element factoid for you: Not all iron is magnetic.The a allotrope is magnetic, yet when the temperature increases so that the a form changes to the b form, the magnetism disappears even though the lattice doesn''t change.

Magnetic separation takes advantage of the magnetic difference of different minerals and veins and separate under magnetic effect. It is not only used in the concentration process for magnetite, hematite, manganese, ilmenite, but also used for iron removal operation for coal, nonmetalliferous ores as well as construction material.
· The small iron particles embedded in the slag could be removed by fine grinding and magnetic separation process. The grade of TiO 2 in the obtained high-grade titanium slag reached 60.68% and the total recovery of TiO 2 was 91.25%, which could be directly applied for producing titanium white by the sulfuric acid process.
Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
small magnetic molybdenum ore separation processing line in algeria LINGJUN machinery has been in the mining industry for more than 50 years. The main production equipment includes six series of crushing equipment, sand making equipment, grinding equipment, mineral processing equipment, building materials equipment, and other equipment.
