Energy Efficient Tehnologies for the Mining Industry
CIM Vancouver 2010
Andrew Bamber, Malcolm Scoble,
The availability of inexpensive power has lead promoted the design of mining and processing systems that do not represent state of the art with respect to energy efficiency. Recent trends of increasing energy cost plus the potential for shortfalls in the supply of electrical energy has lead to a reassessment of the importance of energy efficiency in the design of future mining operations. Energy efficiency can be improved in two ways - firstly through improved operating practices and secondly though the application of more energy efficeint technologies. In British Columbia, about 5% of all of the electrical power generated is consumed by mining operations and 70% of this power is used for comminution. The presentation reviews the opportunities to improve energy efficiency and describes some technologies that can signficantly reduce energy demand.
