Principles and practice of sulphide mineral flotation

Synopsis. This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristics.

Flotation and Leaching Studies on Processing of El

flotation and leaching techniques on El-Magharah coal for enhancing ash reduction and desulphurization. A low rank coal sample of El-Magharah coal (22.5% ash, and 3.54% total sulphur) was subjected to a flotation process to reduce ash and total sulphur. Subsequently, a clean coal of 13% ash and 2.14% total sulphur was obtained. The
