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

The removal of phosphorus from reject water in a municipal

Iron‐reducing bacteria ensured the production of ferrous ions from iron ore up to concentrations of 550 mg L −1. The ferrous production rate was linearly dependent on the calculated specific surface area of the iron ore particles. The phosphorus concentration in the reject water was reduced by 90% during bioreduction of iron ore. The
