First choice for HPGR technology and service
HPGR grinding significantly enhances overall throughput This results in the creation of a large proportion of finished product and the reduced Bond Work Index of the pressed material This generally allows for a reduction in the projected number of equipment units in tertiary crushing, quaternary crushing and grindingAll of those applications confirm the early assessments, ie using HPGR within the crushing stages (most typically as a tertiary crusher) shows significant benefits for improving the overall hydrometallurgical parameters The following presentation will discuss the current experience and provide an outlook for HPGR in heap leachingKEYNOTE: HPGR in Gold Leach Applications – an Overview high heap gold leach recoveries, HPGR as a tertiary crusher has been shown to reduce overall capital and operating costs in addition to improving gold recovery An excellent case of this is the Soledad Mountain described by Klingmann (2005) already referred to above HPGR can Real and Potential Metallurgical Benefits of HPGR in Hard
