In nature minerals of interest exist physically and chemically combined with the host rock. Removal of the unwanted gangue to increase the concentration of mineral in an economically viable manner is the basic of mineral processing operations. This book treats the strategy of benefication as a combination of unit operations. Each unit process and its operation is therefore treated separately. Integration of these units leading to the development of viable flow sheets that meets the final objective, is then indicated.

The greatest challenge to a mineral processor is to produce high grade concentrates consistently at maximum recovery from the ore body. To quantify recovery a reasonable idea of the initial concentration of mineral in a lode is required. Proper sampling representing the ore body is therefore essential. The book therefore commences with the techniques of sampling of ore followed by the design and operation of unit processes of comminution that help to release the mineral from the associated rocks. Separation and concentration processes using techniques involving screening, classification, solid – liquid separations, gravity separation and flotation then follow. In the book some carly methods of operation have been included and the modern methods highlighted
