Poorni and Natarajan (2013) investigated the role of B. subtilis, and the adaptation of B. subtilis, in the beneficiation of a de-slimed bauxite ore. In flocculation trials, corundum-adapted B. subtilis cells were able to facilitate the removal of approximately 96% of iron after 5 min interaction at pH 7 to 9.

It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.

Studies were undertaken at R&D to develop a suitable process flowsheet for upgrading the ore for lowering the alumina to below 2% for use in sintermaking. Characterisation studies of the ores revealed that the alumina was contributed mostly by platy shale clay, the iron minerals mostly by martite and hematite and silica by quartz. Clay and iron ...

Beneficiation of alumina rich iron ore slimes is a major challenge for the Indian iron ore industry. High alumina is deleterious for the performance of both blast furnace as well as sintering plants. Slimes generally contain 5 – 10% alumina, and hence despite assaying as high as 60% Fe, those are dumped in tailing ponds.

1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
