Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high-grade concentrate with very low levels of impurities.
A powerful iron ore classification system is a critical prerequisite. Without a sufficiently and appropriately characterised resource, modelling will be inaccurate reducing an organisations ability to implement cost reductions and productivity gains across the iron ore value chain.
01-01-2015· Low-grade hematite ores need to be upgraded to achieve the required iron content, which involves more complicated ore beneficiation processes. The level of comminution required for the low-grade hematite ore is similar to high-grade ores to deliver the same products, lumps and fines.

31-12-2018· Approximately 96% of Australia's iron ore exports are high-grade hematite, the bulk of which has been mined from deposits in the Hamersley province of Western Australia. The Brockman Iron Formation in this province is the most significant host for high-grade hematite iron ore deposits.
As part of CSIRO’s continued contribution to the iron ore industry, we are proud to announce we will be cohosting Iron Ore 2017 at the Perth Convention and Exhibition Centre, 24-26 July. At the event, the Carbon Steel Futures team will present recent work including papers on goethite classification, mineralogical characterisation, and microwave treatment of low-grade goethite ores.

A co-operative research project, combining Commonwealth Scientific and Industrial Research Organisation (CSIRO) research scientists findings and company iron ore geologists’ expertise, resulted in new concepts about the origins, distribution and complexitie of iron ores and their parent rocks (banded iron-formation or BIF) in the Hamersley Iron Province of Western Australia.
Classification of ore deposits - SlideShare. 22/10/2017 Classifications based on the morphology of the ore body could be quite useful, but have a tendency to mix apples with oranges (two ore bodies of similar shapes may be very different in type of ore, texture, origin, temperature of formation etc.).
sharp classification efficiency with low values of imperfection around 0.20 was obtained. Consequently, the response of the lower grade iron ore sample to FDS application, has vast ... These lower-grade iron ore fines are typically rich in Alumina and Silica.
Laser-induced breakdown spectroscopy (LIBS) integrated with random forest (RF) was developed and applied to the identification and discrimination of ten iron ore grades. The classification and recognition of the iron ore grade were completed using their chemical properties and compositions. In addition, two

Special Report: Declining iron ore grades globally and the rising demand from steelmakers for higher grade product is creating the perfect storm for explorers with the goods. In Australia, hematite has been the dominant iron ore mined since the early 1960s, accounting for about 96 per cent of the country’s iron ore …

The result has seen much wider and more volatile differentials between iron ore indices of different grades, and companies exposed to prices such as the high-grade MBIOI-65-BZ and MBIOI-CO are now calling for exchanges to list contracts settled against those indices to help manage price risk, with the basis risk to the 62% Fe financial benchmark deemed unmanageable.
