Abstract. In the flotation of magnesite ore, dolomite dissolution and poor water quality can lead to the accumulation of Ca 2+ in backwater and a slurry of flotation, which can give rise to many problems in the separation of magnesite, dolomite and quartz. This research analysed the effect and mechanism of Ca 2+ on the anionic/cationic ...
Magnesite usually forms during the alteration of magnesium-rich rocks or carbonate rocks by metamorphism or chemical weathering. Magnesites can be divided into three categories based on their crystal characteristics and metallogenic environment.
