A method for beneficiation of magnesite ore wherein the ore is subjected to calcination to decrease the bulk density of the magnesite relative to the gangue. accordingly, after such calcination, conventional gravimetric separations can be conducted with greatly increased efficiency. when the calcination is conducted in a reducing atmosphere, initially nonmagnetic.
Almost all the chemical beneficiation methods consist in solubilising the magnesium content of the magnesite, filtering off the gangue material, purifying the process liquor and finally precipitating magnesium as magnesium carbonate. the chemically beneficiated magnesite is very pure and high grade and can be further processed to.
