In this stage, the main equipment is floatation, agitation tank, thickener. The following two methods is the designed magnesite flotation process by Xinhai.
Both magnesite and calcite are carbonate minerals with high solubility in slurry. The dissolution of these minerals releases metal ions into the flotation system, which adsorb onto mineral surfaces, causing their properties to converge and complicating the separation process [21], [22].Chelating reagents can selectively bind Ca 2+ and Mg 2+ ions in the slurry, showing promising …
