01.02.2014Energy costs typically comprise one of the largest ongoing costs of mining operations, of which 70% is devoted to the comminution of the ore (Norgate and Jahanshahi, 2010). Furthermore, the most significant energy cost occurs in the grinding circuit of the Milling section, where up to 97% of the energy cost is incurred (Ballantyne et al., 2012).

Chemical Industry Carbon Materials Spherical Graphite. Spherical graphite (SPG) is ideal for use as a raw material for anodes. Its smooth, small surface prevents flaking and ensures low irreversible capacity loss and long service life. Due to its high tap density, high charging is achieved and consequently energy density is higher.
