Run-of-mine ore processing is a method of added value in which undesirable gangue-bearing minerals are discarded to obtain the desired minerals. Mineral processing has tangible benefits including savings in freight and handling, and the recovery of metal values from the slag as well as intangible benefits such as mineral conservation, environment protection by filling the mine using gangue-bearing minerals, and energy saving. This book provides rudimental, theoretical and operational knowledge of mineral processing along with coal characterisation and processing of ores of metallic and industrial minerals. It also explains definitions and techniques, along with basic formulas and practical examples. This book is designed for professionals in geology, mining, mineral, metallurgical and chemical engineering. The eccentric feature of this book is the introduction of simple numerical calculations for evaluation of the processes which in turn help understand the concepts with enhanced clarity and handle day-to-day operations of mineral processing plants. Therefore, it can be used both as a simple reference guide and a concise course in mineral processing.
