Application and evaluation of spiral separators for fine

For fine coal with a size range of0.6 mm, froth flotation is the most commonly used process for coal preparation (Honaker and Mohanty, 1996). The major development in recent years in mechanical flotation cells is the increase in cell size and treatment capacity, and the maximum size of flotation cell is close to 40 m. 3

Optimization of Coal Washery Tailings by Flotation Process

Oct 17, 2021Flotation tailings are by-products 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 applications. 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.
