US3936372A Method for beneficiation of magnesite ore

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 non-magnetic gangue material is converted

Calcination Wikipedia

Calcination refers to heating a solid to high temperatures in air or oxygen, generally for the purpose of removing impurities or volatile substances. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.The root of the word calcination refers to
