The Cracow Gold project is located 500kms north west of Brisbane, Queensland, Australia. This is an abbreviation of the paper “Fine grinding implementation at the Cracow Gold processing plant” (Paz et al), from the AusIMM’s MetPlant 2019 conference, in Perth, Australia. Cracow process flowsheet, incorporating HIGmill technology.

r PolarFit ultra-fine-grinding mill. This versatile grinding system provides a cost-efective way to reduce hard-to-grind materials to smaller particle sizes than can be achi. ved with conven-tional impact mills. The mill generates consistent yields of particles between 45 and 25. microns or between 60 and 325 mesh. In some cases it can prod.
