The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the highgrade ores depleting very fast, the focus is on the beneficiation of lowgrade resources. However, most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable ...

During dry processing of iron ore in Khondbond region of Orrisa, approximately 3040% (by weight) of total feed is produced as fines. These fines are being dumped and get accumulated at mine site as plant reject. Accumulation of fines over the year poses significant environmental impact on land, water, and air.

Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for nearcomplete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

Among the current projects in Brazil is that of Centaurus Metals, who are also planning to install a dry beneficiation line with magnetic separators at their Jambreiro Iron Ore facility, which processes an ore with an iron content of around %. The fact that this type of plant is not necessarily unproblematic is reported, for instance in [9].

The beneficiation of iron ore deposits to yield haematite and magnetite concentrates for steel making processes typically require the use of one or a combination of wet processing techniques based on gravity, magnetic or froth flotation processes. With the need for more costeffective technologies with a lower water demand, a reexamination of dry processing techniques has been initiated.

In mining and minerals industries, whenever water supplies are restricted and also where wet processing leads to problems in handling and dewatering of the products and tailings, dry beneficiation is preferred. Moreover, the decrease in available highgrade iron ores has generated a need to develop alternative beneficiation processes for processing lowgrade iron ores.

ABSTRACT The current beneficiation study examines the potential for separating ultrafine lowgrade iron ore materials using a circulatingtype air classifier. Statistical analysis using Response Surface Methodology (RSM) was implemented for optimization of the separator critical processing parameters to achieve sharp separation at a cut size as fine as 2038 µm. Results demonstrated that it ...
