The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to high-tonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energy-efficient than grinding mills, not requiring steel grinding media, and providing higher Words of welcome Carlos Barahona, Procemin-Geomet 2019 Executive Director; General Manager, Gecamin, Chile Rick Valenta, Procemin-Geomet 2019 Co-Organizer; P rofessor, Program Director Geology, WH Bryan Mining and Geology Research Centre, SMI, University of Queensland, Australia

High Pressure Grinding Rolls (HPGR) have been used for over 20 years, however the technology has not received wide industry acceptance despite reports of substantial energy advantages. One barrier is that full and fair consideration cannot be given to HPGR-based comminution circuits for early-stage mining projects, because industry standard tests require large sample sizes for evaluation of

An overview of the classification systems in hydrocyclones in the copper ore enrichment departments at KGHM Polska Miedź SA was presented. In recent years, IMN has been conducting an investment - replacing hydrocyclones with modern HC hydrocyclone solutions - manufactured by ZAM Kęty and IMN.

Robust HPGR testing will continue to be of critical importance. The leach test facilities of Kappes, Cassiday Associates in Reno include a thyssenkrupp pilot HPGR ("PILOTWAL"). This unit can handle samples as small as 100 kg for trade-off and feasibility studies, but it can process up to 20 tonnes per hour for larger scale testing and semi-commercial purposes.

Overview Oceanic is focused on the development of the Ungava Bay iron properties. These properties comprise 3,703 claims over three project areas, namely Hopes Advance, Morgan Lake and Roberts Lake, which are located over 1,568 km2 along the northern extension of the Labrador Trough in the Nunavik Region of northern Quebec.
