[email protected]With advanced technology, excellent quality and considerate service, it has achieved nationwide coverage and exported to foreign countries.
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, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts, and is a key ingredient in steelmaking.

The major rock types mined for the production of metallic iron are massive hematite,pisolitic goethite/limonite, which provide a 'high-grade' ore, and banded metasedimentary ironstone, magnetite-rich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a 'low-grade' ore. High-grade ore

Nov 11, 2017· Magnetite has higher iron content than hematite. Buthematite ore usually contains large concentrations of hematite; magnetite ore, low concentrations of magnetite. The ore has lower iron content, typically between 25% and 40% Fe. This ore is unsuitable for steel making, and it must be concentratedbefore it can be used toproduce steel. Magnetite ore’s magnetic properties are helpful …

Like magnetite, hematite is an oxide of iron and it has the formula Fe 2 O 3. Hematite is not magnetic, and so is not readily removed from soils to which it has been added. It also can occur naturally in soil. Hematite is the most prevalent oxide of iron present in the ground, as such, it is also the largest source of iron for iron/steel production.

Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.

Jan 31, 2018· It is mainly found in sedimentary rocks. But it is sometimes found in beach sand in large quantities. The major use of magnetite is as a source to extract iron in the form of pig iron or sponge iron form. This produced iron is further used to convert into steel. In addition, magnetite is used as a catalyst.

The plants for theproductionof pigironorsteelare called ironworks. An ironworks (orironworks) is an industrial plant for theproductionofsteelfromironores! Before theironores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing).

Magnetite offers a source supply of material >66 per cent iron grade product, which is used as premium feed (predominantly pellets) to blast furnaces or specialised steel mills. The Iron Bridge project area contains outcropping magnetite and hematite banded iron formation (BIF), which within the region was recognised as having potential to host economic mineralisation during the 1960s.
