paste thickeners for coal preparation plants pdf
Coal processing - Mining | Bulga CoalThe coal is then transported from site to the Port of Newcastle via rail for export. In 2010, the Preparation Plant successfully installed a paste thickener, the first of its kind in coal processing. The aim of the paste thickener is to thicken tailings which saves on water, power and reduces space required for tailing storage.Improving the Efficiency of the Tailings Thickener in Coal ...PDF Company Brochure ...
