Magnetite Ore, Magnetite Iron Ore, Iron Ore Mining Process

Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from run-of-mine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.

Ground Magnetic Surveys – Seeing Beneath The Rocks ...

Why Is A Ground Magnetic Survey Useful? Ground magnetic surveys map the magnetism of underlying rocks. The most common magnetic minerals found are pyrrhotite, (iron sulphide), and magnetite. Magnetite when found with sufficient purity and quantity may become an iron ore deposit.

Magnetite & Lodestone | Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

Why Is A Ground Magnetic Survey Useful? Ground magnetic surveys map the magnetism of underlying rocks. The most common magnetic minerals found are pyrrhotite, (iron sulphide), and magnetite. Magnetite when found with sufficient purity and quantity may become an iron ore deposit. Pyrrhotite is important because of the minerals it's often associated with including pyrite, another iron sulphide mineral, which may contain gold.

Hematite: A primary ore of iron and a pigment mineral

Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
