The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants). In the process, low grade iron ores are dry-ground, preferably to their liberation size & passed through a fluidized bed roaster.
During mining, beneficiation and transportation of these manganese-bearing ores up to 30% of the ore produced is converted into −10 mm low grade Mn ore fines. Indian manganese ore deposits occur as bedded sedimentary deposits and found in Madhya Pradesh, Maharashtra, Gujarat, Andra Pradesh and Orissa states.
Iron ore is smelted after going through beneficiation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. High-grade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.

The novel beneficiation process is realized according
Low grade Iron Ore Beneficiation and the Process of Jigging. Iron ore resources are getting consumed at an accelerated rate because of the growth in the production of iron and steel. Due to this reason the availability of high grade iron ore is reducing and the supply of high grade iron ore to iron and steel plants is declining sharply.

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.

Indian Iron Ore Scenario : Low Grade Iron Ore Beneficiation Anand Kumar, Manager (mining), Omendra Singh, Design Engineer (Mining) MECON Limited, Ranchi
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and
The consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of iron and steel industry. The depletion of high grade iron ore resources make it inevitable to utilize the existing low grade iron ores/fines/tailings with effective beneficiation to meet the present specification and demand. Enormous amounts of fines are produced both from the natural
India and China, raw materials used are low grade iron ore. This is done to solve the problem of expensive raw materials iron ore and iron ore reserve potential that exists [1]. In India, for economic reasons and increased efficiency of blast furnaces, elevated levels or beneficiation process plays an important role [2]. Various techniques are

techniques for the beneficiation of a Sudanese iron ore, the newly discovered Wadi Halfa iron ore deposit. It is a low-grade type of ore with high silica content, more than 45% SiO 2, and an average iron content of about 35% Fe. Based on the fact that there are appreciable differences
In addition, it is revealed that low-grade iron ore with a high pore properties, α-FeOOH content, and gangue content can be upgraded to a high-grade iron ore with a low pore property (low specific surface area and pore volume), high Fe 2 O 3 content, and low gangue content using the above method. Therefore, this method is promising as a method
Iron Ore Beneficiation Process. During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being
4.1.2 Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sand-like iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation. Crude ore is commonly mixed with other minerals (gangue), which reduce the iron content.
