iron ore processing and manufacturing

In 2010 magnetite accounted for approximately 30% of global iron furnace feed for steel production. In Australia, this figure was only 3%. Iron ore beneficiation processes and other mineral processing operations with magnetite in the ore require accurate mass flow measurements to properly balance the grinding and separation circuits as well as to determine the true throughput impact of circuit changes. Determination of the mass flow requires an accurate measurement of the volumetric flow rate and the specific gravity of the slurry.

the importance of magnetite ore processing

The cost to process ore is very important for all mining projects and can vary greatly depending on the individual ore type. This is also true for magnetite projects. The two most important characteristics of magnetite ore that effect processing costs are grind size and hardness. The grind size is the size that the ore needs to be ground to, to release a quality magnetite product. It is generally between 150 and 25 microns (100 microns = 1 tenth of a millimetre).

More importantly the hardness of the ore determines how much power, and therefore cost, is required to reach the optimum grind size. The hardness of ore is expressed as the Bond Work Index in units of kilowatt hours per tonne (kwh/t). The smaller this number the less power used in crushing and grinding. A guide to the variability within magnetite projects is shown in the graph below from available data.
