The iron mineral in the single magnetite – hematite (siderite) contains magnetite and hematite or siderite, most of which are fine-grained disseminated. The gangue minerals are mainly quartz, some of which contain more ferrosilite. The proportion of magnet in this ore varies and increases gradually from the surface to the deep of the deposit.
The ore has high iron content, typically between 56% and 64% Fe. Magnetite has higher iron content than hematite. But hematite 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.

The mineral magnetite actually has higher iron content than the mineral hematite. However, while hematite ore generally contains large concentrations of hematite, magnetite ore generally holds low concentrations of magnetite. As a result, this type of iron ore ore must be concentrated before it can be used to produce steel.
Answer (1 of 2): Hematite is Fe2O3 - Oxidized Iron. 69.9% Magnetite is Fe2+(Fe3+)2(O2-)4 - Oxidized Iron. 72.4 % Fe. Siderite is FeCO3 - Oxidized Iron. 48% Fe. Limonite is (FeO(OH)·nH2O) - Oxidized Iron. 59.8% Fe. Ankerite is Ca (Mg, Fe2+, Mn) (CO3)2 - Oxidized Iron. ~15% Fe. Goethite is Fe3...

Siderite is a hard and dense iron carbonate that contains no sulfur or phosphorus and is mixed with carbonates such as magnesium, manganese and calcium. Siderite is roughly equivalent to calcite, but with iron instead of calcium. · Siderite chemical formula: FeCO3 · Iron content: up to 48.2% · Siderite color: gray, tan
Correct option is D) Different types of iron ore contains varying percentage of pure iron. Magnetite, haematite, limonite, siderite are the ores of Iron. Magnetite is the best quality of iron ore and contains 72% pure iron. Haematite contains 60% to 70% pure iron ore. Limonite contains 40% to 60% pure iron.
Siderite is a hard and dense carbonate of iron, containing no sulfur or phosphorus and is mixed with carbonates such as magnesium, manganese, and calcium.

It is known that strongly magnetic magnetite (Fe 3 O 4) can be easily separated from nonmagnetic components of magnetite's quartzite. In contrast, ore is difficult to beneficiate if it contains weakly magnetic siderite (FeCO3), goethite (FeOOH), or hematite (Fe2 O 3) as a main iron-bearing mineral.
