Enhancement of gold agitation leaching by HPGR

2020-12-1  Studies using the HPGR on heap leach copper ores from Chile and the US have shown that the copper leachability of the coarser ore particles was better after high pressure grinding (Daniel, 2007, Klymowsky et al., 2002). However, studies of HPGR on finer ore particles are very rare, particularly in the leaching of fine size fractions.
