Feb 21 2020 Iron ore mining often focuses on looking for hematite deposits known as red iron ore and magnetite as they have naturally weak magnetic fields that aid in their purifiion. Hematite however responds better to the flotation process in iron ore beneficiation than magnetite so it is the preferred type of ore.

Magnetite Amp; 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. Todays commercial taconites contain 25 to 30 iron by weight.

Comparison Of A Low‐Cost Magneto‐Inductive

magnetic deposits generate a magnetic field anomaly which exceeds 100 nT this resolution is not needed for detecting such large signals. The recently introduced magneto-inductive technology has led to the development of a low-cost magnetome-ter that can measure the ground magnetic field up to a resolution of around 10 nT.
