The separation of magnesite and dolomite has always been a difficult problem in flotation production, one of the reasons is that the dissolved Ca²⁺ ions from dolomite weaken the anionic ...
Occurrence. Magnesite occurs as veins in and an alteration product of ultramafic rocks, serpentinite and other magnesium rich rock types in both contact and regional metamorphic terrains. These magnesites are often cryptocrystalline and contain silica in the form of opal or chert . Magnesite is also present within the regolith above ultramafic ...

Fused Magnesia Production Process. Magnesite (magnesium carbonate MgCO 3) is converted into magnesia by the application of heat which drives off carbon dioxide (CO 2 ), thereby converting the carbonate to the oxide of magnesium (MgO). Magnesite, from both natural sources (primarily magnesite) and synthetic sources …
namely, thermal, electrolytic and wet methods.13 Because thermal and electrolytic methods consume a large amount of energy and cannot be used on an industrial scale, magnesite is usually leached using a hydrometallurgical process.14 Wet metallurgy is the transfer of the desired metal from the raw material into the liquid phase by a chemical reac-
