    The magnetic susceptibility (MS) is the ratio of the material magnetization to an outer magnetic field. This volume susceptibility (often k, dimensionless in SI) differentiates paramagnetic ( 0), diamagnetic ( 0), ferro- and ferrimagnetic (≫ 0) materials. In rocks it spans a huge value range of more than seven orders of magnitude

    The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio
