Mining. There is significant potential to reduce energy costs in mining through an integrated approach to energyefficiency investment. Applying energyefficiency strategies to comminution, the largest area of energy usage, usually offers the best scope for savings. Opportunities for energy savings exist in other areas including:
a grinding mill which is suitable for the purpose would be one of the main requirements for costeffective and troublefree material processing if a ... Powdered charcoal or coal for fuel briquettes < Pigments for Paints (various materials) ~ Silica quartz (glass making) Phosphate (fertiliser) Iron Ore
The Hardgrove grindability index (HGI) is a widely used coalquality parameter with applications in coal mining, beneficiation, and utilization. An understanding of the petrology of the coal is fundamental to understanding the validity of the HGI in the given application. The HGI varies with coal rank, increasing (greater ease of grinding) with increasing rank through the highvolatile ...
