A paper presented at the 45th Annual Canadian Mineral Processors Operators Conference in Ottawa Canada this year has received the 2013 CEEC Medal. C. Wang, S. Nadolski, O. Mejia, J. Drozdiak, B. Klein co-authored the paper titled Energy and Cost Comparisons of HPGR based circuits with the SABC circuit installed at the Huckleberry Mine. It summarises a comprehensive energy and cost study comparing an existing SAG mill based circuit at Huckleberry with two proposed circuits involving comminution technologies which are associated with energy efficiency; high pressure grinding rolls (HPGR) and high speed stirred mills.

 It was concluded that the energy reduction for the new flowsheets significantly improved the economics of the Huckleberry comminution duty.

“Congratulations to Fisher Wang, Stefan Nadolski, Olav Mejia, Jeff Drozdiak and Bern Klein on their excellent work. The business of energy efficiency in grinding and crushing is a global issue and we are delighted that the authors of the prestigious 2013 CEEC Medal produced their outstanding paper as a result of an industry first; collaboration between BC Hydro , University of British Columbia and the mine operator Huckleberry Mines. The 2013 Medal recipients are based in North America, specifically in Vancouver, and they join previous CEEC Medal recipients based in Peru, Chile and Australia.” said CEEC Chair, Elizabeth Lewis-Gray.
