Iron ore extraction in India yields lumps to fines in the ratio of 2:3 — 60% of the ore generation is in the form of iron ore fines. For efficient utilization, it is imperative to process these fines. The push towards the beneficiation of low-grade iron ore could reshape trade patterns if effectively implemented.
The pelletisation industry procures iron ore dumps of 45 % Fe at Rs 500/ tonne and through process of beneficiation gets one tonne of ore of 61 % Fe at cost around Rs 2,000.This includes the cost of 2.5 tonnes of dump and beneficiation cost.

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, …
Iron ore beneficiation has lagged in India because of challenges such as the area required for tailings and transportation costs, state-controlled mining firm NMDC technical director Vinay Kumar said. Tailings refer to the waste generated by the beneficiation process. Constructing more slurry pipelines would reduce logistics expenses, Kumar added.
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.
