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.

For Australian iron ore grades, a major difficulty is that grades are estimated based on saleable production and not raw ore, despite the majority of iron ore requiring beneficiation before use (Mudd, 2009a, 2010b). Despite the issues with the data, the long-term trend is a gradual ore grade decline for saleable iron ore.

Mining (extraction), beneficiation, and processing of iron ore produces iron and steel. Mining is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. High grade iron ores (iron content greater than 62 %) are simply crushed, screened and shipped directly to the iron making unit (e.g. blast furnace).
