دانلود کتاب MetPlant Conference Proceedings 2008 - Metallurgical Plant Design and Operating Strategies

This 2008 conference is the sixth in the series on the state-of-the-art advances in metallurgical processing of ores. Topics covered include plant design from test work, establishing successful design teams to meet client requirements, designing and building greenfield plants, plant expansions and retrofits, use of new technologies in processing ores, plant control and sampling, maintenance and the whole-of-life of operations through to site closure, and water and tailings management. The keynote addresses the role of the metallurgist in project development, the design and building of new plants, and a more rigorous approach to metallurgical accounting. The papers in the proceedings cover developments in design and operation across comminution, gravity, hydrometallurgy, flotation, water recovery, modelling and control. They provide insights into the conceptual thinking and methodologies now used by design engineers, consultants and plant metallurgists in the way plants are built, operated and upgraded to higher tonnage, greater efficiency and lower operating cost.
