Full Description
Mineral Beneficiation or ore dressing of run-of-mine ore is an upgrading process to achieve uniform quality, size and maximum tenor ore through the removal of less valuable material. Beneficiation benefits the costs of freight, handling, and extraction (smelting) reduce, and the loss of metal through slag. Usually carried out at the mine site, it saves time and costs and allows selective, profitable bulk mining. This practical guide presents the essentials of mineral dressing and its support operations. It explains the terms and techniques and provides basic formulas, methods and practical examples for calculations to be made on site. Intended for professionals in mining and mineral engineering (mining, metallurgical and chemical engineers, geologists). It can be used both as a simple reference guide and as a concise course on beneficiation.
