HPGR helps you to get more value from every ton of ore with the sheer production capacity and state-of-the-art features. They can be used in a wide range of mining applications: Hard rock; Diamond; Iron-ore; Gold; Copper; Platinum; Molybdenum; Industrial minerals; Others
HPGR in Iron Ore Processing • Applied to iron ore industry mainly for regrinding of pellet feed to improve properties in the pelletising process • Over time has been applied to other iron ore processes to improve concentrates • Australia − Magnetite (Karara) − Vanadiferous, Titaniferous Magnetite (Future: Mount Peake) • South Africa
Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid volume, exceeding its compressive

We have now launched HPGRs at Sections 2 and 3, completing the upgrade of the entire beneficiation plant. This will enable us to increase primary iron ore processing up to 37 million mt/y, up by 5 million mt/y in 2013, and become 100% self-sufficient in iron ore feedstock.” Each HPGR unit replaced two conventional crushers.
Developments In Iron Ore Comminution And. Hpgr technology was introduced to the mineral processing industry in the mid-1980s and has rapidly for the mining industry established itself as the convention in the comminution of cement, clinker, slag, iron ore, iron pellet plant feed, and diamond ore.get price
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
Whether in an up market or a down cycle, we'll continue engineering equipment that meets the ever-growing needs of the mining and rock excavation industries, and help you overcome your challenges. Hpgr Crusher In Iron Ore Mines valdichianamusei
HPGR in coarse ore was commissioned at Los Colorados in 1998, there were only 14 HPGRs installed in the minerals industry, mainly for grinding pellet feed to increase the Blaine value [Van der Meer et al., 1997], and only three KHD HPGR units were applied for crushing coarse ore.
leaches ore that is fine-crushed using vertical shaft impact crushers. For pure heap leach projects, significant recovery and recovery rate improvements have been demonstrated on certain ores when HPGR is applied yielding a rapid payback on the extra capital of installing HPGR. In other cases, where an ore requires tertiary or quaternary
Fortuna Silver Mines, which recently began commissioning and ramp-up at its $320 million Lindero gold project in Argentina, included HPGRs in its tertiary ore crushing circuit, based on testwork that indicated HPGR-processed ore would provide higher extraction rates than that obtained using conventional cone crushers or a vertical shaft impactor (VSI).
It may have seemed quite the leap of faith: the biggest HPGR ever built for a gold heap leach operation; the first F-Series HPGR we had ever built, and the only HPGR operating in hard rock mining in the region. But it was a leap the team at Ivrindi Gold were prepared to take
Such a system should preferably be installed as close as possible to the HPGR, preferentially directly ahead of the HPGR feed chute.” In circuits with particularly heterogenous ore competencies, such as transition gold ores or coarsely-banded iron ores, HPGRs should be run at variable speeds to ensure throughput is maintained regardless of
largely in iron ore and diamond treatment. In these industries, the application of HPGR ranges from coarse grinding, e.g. the grinding of 65mm (2.5”) size excess pebbles in AG circulation loops, to final grinding of <100μm material to high Blaine values in the preparation of pellet feed. KHD has a history of successfully installed HPGR units
