Mineral Processing Design and Operation

        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

Boddington gold mine in Western Australian mining video

This is animation video the Boddington gold mine is located in Western Australian mining some 14 km northwest of the town is located about 130km south-east of PerthThe town's. Western Australia occupies the whole western part of the continent. Its economy is largely driven by extraction and processing of a diverse range of mineral and petroleum commodities. The state contributes an estimated 58 percent of Australia's Mineral and Energy Exports.
 Newmont Boddington Gold mine, commenced plant start-up in July 2009. Over 14,000 employees and contractors worked more than 14 million man hours to start up the project the gold mine in the Boddington At year end 2010 the mine had reserves of 20 million ounces of gold and 2.4 billion pounds of copper. At full production Boddington would be Australia's largest gold producer.
