Australia’s Iron Ore Product Quality
A Report on the Quality of Iron Ore Resources in Australia : Geoscience Australia Onshore Minerals and Energy Division Author: Richard O’Brien 2009 Abstract : Australia’s iron ore production has seen strong growth over the past five decades and over this period of time a very significant change in the blend of Australian iron ore production has occurred Initially there was a clear The highthroughput operation will remove beneficiated magnetite fines at 120mesh, 200mesh and 325mesh and increase iron concentration The company chose the Whirlwind air classifier because, says Sturtevant, “of its dry air classification processFortescue Metals chooses dry classification to upgrade 1/11/2018 “We expect that GDP growth will be preserved at the expense of air quality but that productive ores will mitigate some of the pollution as a larger production base will reduce emissions on a pertonne of pig iron basis” And big premiums for high grade, low impurity iron ore are here to stay, says explorer Flinders Mines (ASX:FMS), which is searching for a way to upgrade the product at its China wants more top quality iron ore and these ASX
Magnetite Wikipedia
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself It is the most magnetic of all the naturally occurring minerals on Earth Naturally magnetized pieces of magnetiteIntroduction Iron ore Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)n(H 2 O)) or siderite (FeCO 3)Roughly 98% of iron ore on the global market is Environmental impact of iron ore mining Wikipedia1833 Magnetite Magnetite appears to be the main deposit on oil and gas production systems under high temperature conditions >150°C (302°F) and anoxic conditions, especially on carbon steels [31,32]Magnetite an overview ScienceDirect Topics

Magnetic separation : ALS
All magnetite ore bodies will require some magnetic separation investigation ALS regularly performs the following magnetic separation tests: Davis Tube Recovery (DTR) tests on stage pulverised samples ; Davis Tube optimisation tests versus grind size; Dry or wet LIMS tests; MIMS tests; WHIMS tests; ALS provides large scale, continuous integrated pilot facilities for confirmation of batch test 2/4/2019 Magnetite ore bodies can be competitively large but they host lower grades The background grade at Iron Bridge, for example, is 30 per cent The background grade at Iron Bridge, for example, is Iron Bridge is the next path to Fortescue's quality street1/11/2018 “We expect that GDP growth will be preserved at the expense of air quality but that productive ores will mitigate some of the pollution as a larger production base will reduce emissions on a pertonne of pig iron basis” And big premiums for high grade, low impurity iron ore are here to stay, says explorer Flinders Mines (ASX:FMS), which is searching for a way to upgrade the product at its China wants more top quality iron ore and these ASX
