Large numbers of iron ore mines are in operation in Orissa, India to meet the internal and export demand of iron ore for iron and steel making. During the process of mining relatively lower grade iron ore containing 56-58% Fe is also being generated and stockpiled separately due to less market and industrial value. The accumulation of these lower grade lumps and fines are increasing day by day due to increase in the regular production of iron ore for steel industries. Simple washing of these low grade ores by scrubbing could not upgrade the iron content as evidenced from some laboratory studies.
However the utility of these ores in sinter or pellet making have urged many laboratories in India to undertake systematic studies for recovering iron values from these low-grade ores.
Pelletizing plant iron ore involves different types of equipment. The main areas or processes are the hub, ball, induration and handling. The concentrator is where the ore is ground to a fine particle size typically 80 % - 45 micron powder and other impurities separated by magnetic separation and flotation . The area of agglomeration is where the powder ore is mixed with water, a binder and rolled in rotating drums to create spherical balls . The area of induration fact can be broken down into three areas: grid, oven, cooler. The grate surface is where the pellets are dried and the curing process is started. Pellets at this stage are more stable and can be stored in the oven without braking. The oven is used to conduct heat in the pellets to force the reaction throughout the pellet. In an effort to recover all of the heat that is present in the pellet after the oven, the granules fall into a cooling device .
Hematite is weak magnetic associated ore. The Mohs hardness of the hematite is 6. The flow of the technics would be: 1st stage ore washing--storage--1st stage crushing--2nd stage crushing--3rd stage crushing--2nd stage ore washing--storage--feeding ore into rotary kiln--magnetizing roasting--ore cooling--storage--ore milling--magnetic separation--dehydrate--fine ore.
