Iron Ore Mining Which Is Better Hematite Magnetite

Mineralogical studies have established that the main iron-bearing mineral is hematite, which contains 69.02 to 70.35% of iron distributed in the ore. Magnetite and hydrogoethite account for 16.71–17.74 and 8.04–10.50% of the component, respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides is very insignificant.

Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower. Deposits with less than 30 percent iron are commercially unattractive, and, although some ores contain as much as 66 percent iron, there are …

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.

Feb 24, 2015 The majority of steel production is supported by iron ore sourced from high-grade hematite deposits, although a significant fraction comes from magnetite deposits. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits require significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix.

As opposed to hematite iron ore that is traditionally mined in Western Australia, magnetite ore requires beneficiation before it can be exported for use in the steelmaking process. Once this occurs, the resulting concentrate is a premium feedstock for steel mills.

The Brockman Iron Formation in the Hamersley province is a significant example of high grade hematite iron ore deposits. Magnetite is an iron oxide mineral which is generally black in colour and highly magnetic, the latter property aiding in the beneficiation of magnetite ores. Magnetite mineral contains 72.4% iron, which is higher than hematite but the presence of impurities results in lower ore grade, …

May 24, 2020 There are two main types of iron ores – hematite and magnetite. Hematite is higher grade in the ground, while magnetite deposits are large and quite low grade – but produce very high-grade products. Grade is king. Grade doesn’t mean much to those not in the mining game, but to producers there are several reasons why it is key to the profitability of their operations. Iron ore mining is a high …
