Alumina reduction in Rajhara iron ore slimes essentially involves separation of hematite from gibbsite in relatively coarser fraction and from kaolinite in the finer fraction. Selective dispersion flocculation studies on synthetic mixtures clearly indicated that while it was possible to achieve almost perfect separation of hematite from kaolinite using starch and …

The iron ore fines sample was collected from the spiral classifier overflow of a typical Iron ore beneficiation plant of Noamundi, India. The sample was dried, thoroughly mixed and analysis indicated that the dried sample contained 59.77% of total iron, 5.89% alumina and 4.71% silica with an LOI (Loss on Ignition) of 5.53%.

The main component of bauxite is Al 2 O 3, containing a small amount of Fe 2 O 3, SiO 2, and other impurities. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, and also to increase the alumina content. In addition, bauxite beneficiation can also be used for iron extraction or iron removal.

For 1 t of metal production, approximately 2 t of alumina is required, which is obtained through processing 5–6 t of bauxite ore. Large amount of power is consumed for smelting of aluminum, which is mostly provided by coal-based power plants. For this, about 8–12 t of coal is needed per ton of aluminum produced.

In many lithium ore beneficiation plants, it is a common practice to de-slime the ore prior to flotation. De-sliming is typically carried out to remove the −20 µm size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit (Bale and May, 1989). As is the case in many operations, de-sliming is ...
