Water and energy assessment for dewatering in opencast mines

01/12/2014  Energy cost is important for controlling the cost of production in any industrial process. For mining, it accounts for about 15% of the total cost of production (Colorado efficiency guide, 2013). Energy cost for dewatering is significant in opencast mines and can be minimised by reducing the specific energy consumption (SEC). The SEC varies ...
