Optimization of Coal Washery Tailings by Flotation Process

4 days ago · Flotation tailings are byproducts of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their appliions. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation tailings compared with raw coal.
