Magnesium Carbonate (Mg) Carbonate (salt-type mineral) is a typical gangue phase, associated with a variety of valuable minerals, and complex to process. Dolomite and magnesite are the main magnesium carbonates, and they can be associated with other salt minerals, including phosphates (apatite), sulfates (barite), halides (fluorite), and tungstates ( scheelite), as well as sulfides and other oxides. So, how to process magnesium carbonate

Magnesium carbonate processing method

The ease with which magnesium carbonate can be separated from its associated valuable minerals depends on various processing conditions. In order to achieve sufficient separation efficiency, different treatment methods based on the properties of valuable minerals are used: magnetic separation, gravity separation, electroseparation (when iron and titanium oxides are valuable minerals), calcination and froth flotation.

The froth flotation technology is considered to be one of the more effective mineral processing methods for carbonate minerals. While flotation separation of magnesium carbonate from non-salt minerals is relatively effective, the beneficiation process is significantly more difficult when associated with salt minerals. Therefore, several parameters (particle size, surface properties, solubility, collector type and concentration, modifier type and its concentration, etc.) must be fully optimized to achieve effective flotation separation.
