Dry processing of magnetic iron ores
The iron ore industry has reached the end of an unprecedented period of expansion triggered by China's demand for iron ore. Lower ore prices have led producers to focus on optimising mining operations while extracting the maximum tonnage from the infrastructure presently in place or from projects already underway. A rising global surplus is expected …

Iron Ore Processing: From Extraction to Manufacturing
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

The impact of short-term variability of deposits for iron ore processing
Materials handling – wet and sticky ore. As above-water-table, high-grade ore deposits decrease in abundance, and producers increasingly start to extract ore from below the water table, the wet and sticky ore problem is having an increasing impact on the iron ore value chain. Wet and sticky ore can lead to a disrupted flow during processing ...

Processing
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.
