An overland conveyor system transports the ore over a distance of 4km to the beneficiation plant at Germano. Germano beneficiation plant At the Germano beneficiation plant the ore is screened, crushed and classified to feed the primary mills. This circuit assures sufficient reduction of the iron ore particles.
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
Beneficiation of fine iron ore fines was studied in Kelsey Jig. A constant pulp density (25% solids) of the feed slurry was maintained in the study. The feed rate was also kept constant at 60 kg/hr (dry solids basis). Magnetite of size -0.853+0.6 mmwas used as ragging material to avoid the pegging of internal screen having an opening of 425 μm.
The following summarizes some common iron ore beneficiation processes according to the different properties of the ore: Strong magnetic iron ore 1.Single magnetite The composition of iron ore of a single magnetite type is simple, and the proportion of iron minerals is very large. Gangue minerals are mostly quartz and silicate minerals.

The PFS was based on the mining and beneficiation of detritals and CID ore at a design plant throughput of 37.5 Mt/y, with a mine life in excess of 20 years at a nominal 18 Mt/y production. The PFS envisaged that both detritals and CID will be processed as a fines only (-8 mm) product, with the CID material being processed on a campaign basis.

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite …
The results obtain indicate that it is possible to beneficiate low grade hematitic iron ore from a feed of 50.74% Fe to 65.11% Fe with an acceptable recovery of 71.88%. …
It involves the dry recovery of iron ore fines and super fines from mining wastes, low grade run of mine (ROM), or compact itabirite. The method does not use water to process iron ore, instead it transforms mining tailings – with low iron content and no commercial value – into high iron content and low contaminants, making it economically viable.

Generally this fine iron ore will be beneficiated to produce a pelletizing concentrate with very strict chemical and physical specifications. In addition, because of the increasing demand for iron ore there are now more opportunities to produce by-product iron ore from mining operations producing other commodities.
Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

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.
