As evident in Fig. 1.2, the world's production of usable (processed) iron ore has increased from about 970 million tons in 2000 to 2.45 billion tons in 2019. Australia is the largest iron ore producing country, producing approximately 919 million tons of usable ore in 2019, equivalent to about 37% of the world's iron ore production.

Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.
