Magnetic iron ore (magnetite) – This contains Fe in the form of Fe3O4. Red iron ore (hematite) contains Fe in the form of Fe2O3 oxide. Brown iron ore – This contains Fe in the form of hydrate. The most common types are limonite (2Fе203 х ЗН2О) and goethite (Fe203 х H20). Siderite (FeC03) is the poorest ore.

Iron ore is the primary raw material used to make steel. Steel is strong, long-lasting and cost-efficient – making it perfect for everything from washing machines to cars, bridges and skyscrapers. According to the World Steel Association, steel is the most commonly used alloy in the world. Global ...
In this study, a batch of magnesia iron ore pellets was first sieved into particle sizes of 8–10 mm, 10–12.7 mm, 12.7–16 mm and 16–20 mm, and the four different size fractions were used to study the effect of pellet size on metallurgical properties.
It takes about 1.6 tons of iron ore to produce 1 ton of pig iron, and iron ore accounts for more than 60% of the cost of pig iron. It can be seen that iron ore stone is also an …
For studying the effect of specific surface area, the binder and moisture contents were maintained at 0.5 and 9.25% respectively and three different iron ore fines with specific surface area 1610 cm 2 /g, 1780 cm 2 /g and 1930 cm 2 /g were used.
Iron processing Ores Britannica. As-mined iron ore contains lumps of varying size, the biggest being more than1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size.

There are many ores of iron found underneath earth and they are known as siderite, magnetite, hematite and limonite. All these are oxides of iron with some more elements associated in small quantities (mostly silicates). As iron ores are oxides, refinement of the ore to remove oxygen is necessary before we can expect to get pure iron.
