Coal flotation is a very complex process that is characterized by a large variation in physical and chemical properties of treated material, i.e. coal and mineral matter. It is the most efficient separation method for coal particles within a narrow size range, normally from 50 m to 600 m (Trahar and Warren, 1976; Humeres and Debacher, 2002).

21-10-2016Flotation is a complex multifaceted process that is widely used for the separation of finely ground minerals. The theory of froth flotation is complex and is not completely understood. This fact has been brought many monitoring challenges in a coal processing plant. To solve those challenges, it is important to understand the effect of different parameters on the fine particle

Keywords: flotation, hydrophobicity, low rank coal, Tween 60, pretreatment Introduction Flotation is widely used in beneficiation of fine coal slimes (0.5 mm) and is based on the difference in hydrophobicity between coal matter and minerals. It is well known that coal particles are usually much more hydrophobic than gangue ones (Drzymala, 2007).
