Located 120km southeast of Coober Pedy, Peculiar Knob is one of the highest-grade iron ore mines in Australia. To date, Peak has shipped 3.6 million dry metric tonnes (dmt) of direct shipping ore (DSO) hematite from Peculiar Knob with 4 …
Sir: We are very thankful for the constructive comments provided by Kneeshaw and Kepert.

At present, the bulk of our iron ore exports would simply not be compatible, as there are too many impurities. Australia exports two main types of iron ore: hematite and magnetite. Hematite is mined in Western Australia's Pilbara. It's a naturally higher-grade ore (56–62 per cent iron) and makes up almost all (96 per cent) of our exports.
Pure hematite contains 69.9% Fe by molecular weight. It has been the dominant iron ore mined in Australia since the early 1960s. Approximately 96% of Australia's iron ore exports are high-grade …

Different …
Iron ore is an aggregate of several iron minerals, the main ones being hematite and magnetite.Iron ore and coal were and remain two key components of the Industrial Revolution, since the modern world depends on the mining and refining of iron ore for the integrity of its physical infrastructure: materials for construction, …
Australia faces a distinct disadvantage due to the quality of its hematite iron ore compared with other nations. DRI-based steelmaking currently requires ores with a …
These deposits currently constitute a significant portion of Australia's iron ore exports. ... The main iron ore mineral was oolitic hematite and the head grade was 37.5% Fe. The ore was ground to 60% passing 74 µm, 1 kg/t sodium silicate added and the ore was processed using a spiral. The spiral tailing was rejected and the concentrate ...
Hematite, also spelled haematite, is a weakly magnetic iron ore with better floatability than magnetite and wide distribution.It is one of the most important raw materials for the extraction of iron. Its composition is complex. In addition to containing a small amount of magnetite, the impurity embedding of haematite has uneven particle size and …
The Hamersley province of northwest Western Australia is one of the world's premier iron ore regions. The high-grade iron ore deposits are mostly hosted within banded iron formation (BIF) sequences of the Brockman and Marra Mamba Iron Formations of the Hamersley Group and consist of two types: martite-microplaty …
After being subjected to geometallurgical evaluation, the iron ores from Singhbhum Bonai-Keonjhar region, eastern India, have been designated as dense martite microplaty hematite high-strength ore (dM-mH-hs ore), massive dense martite microplaty hematite high-strength ore (mdM-mH-hs ore), schistose microplaty hematite low …
Hematite DSO is what Australia's iron ore industry was built upon. Karara, which at the time was a 50:50 joint venture between Perth-based Gindalbie Metals and …

With available technologies, the steel industry's transition towards DRI requires a significant supply of high-grade iron ore, but the typical hematite-goethite ores found in the Pilbara region are not suitable for beneficiation to higher grades. ... The other two iron ore majors in Australia – Rio Tinto and BHP – do not have measurable ...
Huge iron ore deposits in Western Australia's Hamersley Province formed when major tectonic events led to the breakup of supercontinent Columbia and to the …

Australian iron ore faces growing competition in the emerging green iron market from countries and regions that produce higher-grade ore better suited to non …
The world's resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks …
This paper presents a first summary of results of an ongoing study, started some two years ago, of high-grade iron ore deposits in South Africa, India and Brazil, including a comparison with the rather well-studied deposits of the Hamersley Province in Australia. Large, high-grade hematite iron ore bodies hosted by Precambrian banded …
There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep …
Composition: Hematite consists of iron (Fe) and oxygen (O) atoms, with two iron atoms bonded to three oxygen atoms in each formula unit (Fe2O3). Iron Content: Hematite is a rich source of iron, typically …
Australia's biggest miners know the iron ore they produce in the Pilbara is not well suited to low carbon steel. Solutions will cost tens of billions of dollars

Description and properties of common iron ore minerals. Iron ore minerals are rocks or minerals that contain iron in concentrations high enough to be economically extracted. Common iron ore minerals include: Hematite (Fe2O3): Hematite is the most abundant and important iron ore mineral. It is typically steel-gray to black in color and …
Hematite ore has been the primary type of ore mined in Australia since the early 1960s, according to Geoscience Australia. Approximately 96 percent of the continent's iron ore exports are high-grade hematite, and the majority of its reserves are located in the Hamersley province of Western Australia.
Vale's iron ore resources and reserves can be quite high grade, with the reserves at the Carajas mine in the Northern System in particular consisting of about 18 Bt of hematite ore with an average iron ore content of around 65–66% Fe, compared with approximately 62% Fe for the iron ore reserves and resources in Australia.
