The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore.
A later example was the Cornish stamps, consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ore under gravity. The simplest method of separating ore from gangue consists of picking out the individual crystals of each. This is a very tedious process, particularly ...

Our extensive global network of laboratory and metallurgical testing facilities support most of the processes that are used in the exploration and treatment of iron ore.
The separation process is often complex because the minerals in the ore are very similar in composition and crystal structure, such as halite (NaCl) and sylvite (KCl) (Tippin et al., 1999). Therefore, the process requires maximum use of flotation reagents and modifying agents to separate minerals …

· Bayan Obo ore contains mainly bastnaesite, monazite and associated iron, fluorite, calcite, dolomite, barite, and trace amount of columbite. Due to its complex mineral compositions and similar mineral properties, it is difficult to separate and obtain rare earth and fluorite concentrates with high purity by conventional magnetic separation and flotation. In this paper, a stepwise magnetic ...
· Most of the molten iron from a Blast Furnace is used to make different types of steel. Calcination is the process of converting ore into an oxide by heating it strongly. The most important iron ore is hematite. The iron extraction process is a long process which begins with calcination and then followed by a few major steps.
The chemicals react with the minerals and surface in the froth layer causing the junk material to separate from the valuable minerals. Another popular method is known as "smelting." This technique uses both heat and chemicals (mostly iron and sulfur, with silica mixed in) to decompose the ore, while separating and liquefying the copper.
· In some instances there may be enough variation in the specific gravity of different grades of ore to require different factors for each. Thus, in the Lake Superior iron-ore districts curves have been constructed showing the variation in cubic feet per ton with variations in iron content. One of these is shown in figure 11, A.

The process of ore formation is called ore genesis. Ore Preparation. It takes multiple steps to extract the "important" element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore; Since most minerals are not pure metals, further separation methods are required.
Metallic iron is extracted from iron ore minerals and rocks. Ores rich in iron oxides vary in color from bright yellow, dark gray, deep purple, rusty red to bright yellow.
