hrc3000 is a new generation high-pressure grinding roll that eliminates issues found in traditional hpgrs, allowing the mining industry to reach a new level of energy efficiency. the worlds largest hpgr was installed at freeport-mcmorans morenci site in arizona, usa.,high pressure grinding moving ahead in copper iron,vasilkovka gold mining in northern kazakhstan is the site of one of the recent applications in gold ore treatment. the ore has a high concentration of copper, which signifi-cantly complicates gold extraction. the vasilkovskoye mine is estimated to contain 400 t of gold. in this gold plant, two humboldt wedag hpgrs type rp 16-170/180 (roll

HPGR The Nextgen High Pressure Grinding Roll

whether you operate a greenfield or brownfield plant, the best solution for your heap leach process is hpgr . two key characteristics of copper and gold ore crushed by high pressure grinding rolls more fines and micro cracks result in much better recovery rates than conventionally crushed ores. hpgr in iron-ore mining,high pressure grinding rolls for minerals,ever, there are a few notable examples where hpgrs are used for coarse iron ore grinding in chile, mauritania and the usa. the first large scale attempt at applying hpgrs to harder and more abrasive copper and gold ores was in 1996 at sierrita. although this was considered a

Perfecting HardRock High Pressure Grinding Performance

the commissioning and operation of four hpgrs at the cerro verde mine in peru during 2006 was significant in this context. successful operation and a program of product sampling demonstrated the effectiveness of the hpgr in this major copper-gold process plant and helped suppliers to overcome the unproven technology barrier. driving forces,high pressure grinding rollsapplications for,hpgrs are being evaluated now for hard rock applications in the copper and gold mining industries. there this technology offers significant benefits in comminuting competent and abrasive ores. benefits may include reduced energy consumption, lower wear cost, higher throughput in milling circuits, and
