Chromium (Cr) is the 21th most abundant element in the Earth's crust, and almost all Cr is from chromite (FeCr 2 O 4) ore.Natural weathering (e.g. rock corrosion) and industrial activities (e.g. leather tanning, stainless steel welding, plating solutions, and Cr pigment production) are common ways Cr is transmitted to our air, water, soil, and food.

May 16, 2019 · The dissociation degree of chromite monomer in the sample is 95.11%, the magnetism can be used to separate the chromite from the nonmagnetic ores. The gangue minerals, such as enstatite, tremolite, diopside, biotite, also have weak magnetism, affect the grade of magnetic concentrate. It is better to separate it by using gravity separation.
