Abstract. The world's steel industry contributes 7–9% of global greenhouse gas emissions. This is principally from blast furnaces, basic oxygen steelmaking, sintering and pelletising. The push to reduce carbon emissions will see a change, where green high-grade magnetite with ≥68% Fe grade becomes the preferred feedstock for the steel ...

In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.

Magnetite. Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.

Recently, the grade of iron ore deposits has deteriorated and further development of low grade deposits is desired. Presently, the most effective and often followed route taken to utilize such deposits is the provision of beneficiation plants for upgrading iron ore and pelletizing plants for agglomerating.

Implementation of the above recommendations reduced the magnetite losses in the coal washing plants from about 1.64 kg/t to 1.3 kg/t. This in terms of raw coal processed in the cyclone circuit reduced the magnetite consumption by 639 t, resulting in a savings of US$27,500/annum. The cost savings are shown in Table 5.
