What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its abundance. . Iron ore …
Types of Iron Ore Magnetite. The most important and best type of iron ore is magnetite. It has a metallic iron content of 72 percent. Karnataka, Andhra Pradesh, Rajasthan, Tamil Nadu, Goa, and Kerala are among the states where it can be found. Hematite. Hematite is another important iron source.
3. TYPES OF IRON ORES Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red.

Bioleaching can occur directly via microbial contact with ores or indirectly by microbes producing leaching agents. Common applications include copper, uranium, gold and silver, and silica leaching. Bioleaching is used commercially in slope, heap, and in situ leaching with ores placed in piles or left in the ground and irrigated with microbes.
