Effect of Fe2+ on low rank coal flotation using oleic acid

2 1.Introduction. Coal is an important resource in the energy industry [,, ].With the consumption of high-rank coal, Low rank coal(LRC) is playing an increasingly important role which nearly accounts for 50% of the world's total coal reserves [4,5].The low metamorphosis degree of LRC makes it easily broken and slim in mining and beneficiating, producing a large amount of LRC fines [].

Optimization of Coal Washery Tailings by Flotation Process

Flotation 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.
