RULE, C.M.. Energy considerations in the current PGM processing flowsheet utilizing new technologies. J. S. Afr. Inst. Min. Metall. [online]. 2009, vol.109, n.1, pp.39-46. ISSN 2411-9717.
Energy efficiency is currently a significant area of interest due to the Eskom power situation, which led to severe power impacts to the PGM, and indeed whole SA primary industries, in early 2008. Anglo Platinum has focused on energy efficiency for a number of years, especially in the concentrator operational area. New comminution technologies have been aggressively developed, which have shown real metallurgical efficiency gains as well as significant energy efficiency and saving potential for Anglo Platinum's total electrical consumption as the company expands into a growing PGM demand market. This paper illustrates this programme's activities, potential and considerable achievements to date.
