Magnesite (magnesium) Flotation Process
The following two methods is the designed magnesite (magnesium) flotation process by us. High grade magnesite (magnesium) ore flotation process the grinding fine ore will feed into agitation tank and meshed with flotation reagent. Reverse flotation will get the concentrate ore pulp. Then pulp will transport into thickener and reduce the water.
