The HPGR and air classification circuit used 20 - 30 % less energy than the HGPR, screen, ball mill circuit. While VRM was estimated to use 10 - 30 % less energy (depending on the type of VRM ...
Cerro Verde is 95%–110% (Koski et al, 2011) and the fine screen circulating load at Boddington is 80% (Hart et al, 2011). These are rounded off to circulating load (meaning the HPGR feed rate is double the feed rate to the overall circuit). Both operations employ wet screening of fine ore, HPGR: The next-gen High Pressure Grinding Roll

This paper discusses the rationale behind the selection of HPGR technology and discusses comminution circuit design details. BACKGROUND Organized mining has taken place at Cerro Verde since 1977 when Minera Peru commissioned a leaching and solvent extraction/electrowinning facility that processed oxide and secondary sulfide mineralization.
A Cerro Verde expansion used a similar flowsheet as the 2006-commissioned circuit to triple circuit capacity. The expansion circuit includes eight MP1250 cone crushers, eight HPGRs (also 2.4 x 1.7-m units, with 5 MW each), and six ball mills (22 MW each), for installed comminution power of 180 MW. and a nameplate capacity of 240,000 tpd.

Cerro Verde's four HPGR Polycoms 24/17 Cerro Verde is a copper-molybdenum concentrator. The circuit consists of four (4) HPGRs, rolls 2.4 m diameter x 1.65 m wide, working in closed-circuit with eight (8) 3 x 7.3 m wet screens. Each is powered by 2 x 2500 kW variable speed drive units. They were commis-sioned at the end of 2006.

'Acceptance of the HPGR in the hard rock sector has been slow and cautious, but has come to maturity in the successful commissioning of the Cerro Verde project' (Morley C, 2008). High pressure grinding roll (HPGR) technology has been the subject of many technical presentations in the minerals comminution fraternity ever since the
I go fairly often so I know the options quite well. From Cerro verde one can opt for one of 2 4 hour hikes either climbing the Santa Ana or Izalco volcanos. I generally include a short visit then head to the ruta de flores. The park offers a short and easy hike(45 minutes) around the old crater of the Cerro Verde volcano.
