Sep 16, 2020 of HPGR-based circuits [17]. In another work concerning iron ore processing, the high-pressure comminution proved in achieving better liberation results for low-grade ores [18] and an advantage of bed-breakage method over an impact breakage mechanism [19]. Downstream grinding operations of HPGR products are of a significant importance
