Ore Treatment an overview ScienceDirect Topics

Iron ore processing by Rio Tinto in the Pilbara region of Western Australia does not involve any chemical treatment. Flowsheets for the Brockman 2 and Paraburdoo processing plants are given in Figures 8.4 and 8.5 (Kinnel, 2013). The flowsheets are relatively simple. Dry processing involves up to three crushing circuits to produce lump and fines.

SEPARATION EXPERTISE FOR YOUR SUCCESS IN THE IRON

With difficult hematite iron ore, it was also the very fine particle size distribution and high Blaine number that made vacuum filtration economically unsustainable. A throughput requirement as ambitious as theirs, it was calculated, would demand as many as 8-10 filter presses along with the added buffer capacity, energy costs, and machine

Iron ore Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel.

How to Treat Wastewater from Iron and Steel Industry

When chemical treatment is used, the water is generally reused in the mill; it may be passed through cooling towers, especially in the warm weather months. The recovered scale is sintered for use in the Blast furnace or open hearth furnaces. Mill scale is comparable to high grade iron ore and is thus a salvaged material of considerable value.
