Top five iron ore producing companies in 2020 by mining output
Iron ore producing companies supply a vital component of modern industry, with iron ore used across the world primarily as an ingredient in steel manufacturing. The metallic ores, which can vary in colour from dark grey and bright yellow, to purples and reds, comprise around 5% of the Earth’s crust and are commonly found in four main types of deposit, the most frequently mined being hematite.

Understanding Pellets and Pellet Plant Operations
The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for sintering.

Understanding Iron Ores and Mining of 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).
