Dewatering in mineral processing
WebThe main processes that are used in dewatering include dewatering screens, sedimentation, filtering, and thermal drying. These processes increase in difficulty and cost as the particle size... WebAug 1, 2014 · Thickening-dewatering process is widely used for solid–liquid separation in mineral processing plants. Usually, the feed quantity of the thickener is an uncertain variable, so the underflow concentration of the thickener cannot be accurately predicted, which may result in improper operation and high security risk.
