HPGR Mineral Processing Metallurgy

HPGRs first made inroads into diamond processing (where rock fracture along grain lines favored a reduction in diamond breakage during comminution), and in the ironore industry Over the course of the past 20 years HPGR based circuits have Starting in the 1980’s, HPGR was first successfully implemented in the cement industry and is now used across a wide range of mining applications Today, there are more than 200 machines operating in the mining industry around the globe, on more than 150 sites These energyefficient grinding machines are mostly used for processing ironWhy HPGRs are revolutionising mill circuits HPGR and Iron Ore Processing 1 > M i n e r a l P r o c e s s i n g > E n g i n e e r i n g D e s i g n > T r a i n i n g > S p e c i a l i s t S e r v i c e s Mineral Engineering Technical Services Pty Ltd PO Box 5778 St Georges Tce WA 6831 P: (+61 8) 9421 9000 F: (+61 8) 9325 8311 ABN 66 009 357 171 W: metsengineering E: info@metsengineering Insights Session HPGR in the Iron Ore HPGR and Iron Ore Processing SlideShare
