Abstract. Highpressure grinding rolls (HPGR) are an accepted, but continuously expanding, comminution technology. The copper industry has a growing need to process harder ores with progressively lower grades, more challenging metallurgy and increasing demand for efficient bacterial leaching applications.
HPGR provides flexible crushing solutions, as it is suitable for both new installations and upgrades in the mining and construction industry. Moreover, it is a highly energyefficient technology for comminution and involves the shortterm exposure of raw materials such as iron ore to a very high pressure.
The obtained results proved that the application of HPGR devices in given copper ore comminution circuit may improve the effectiveness of downstream grinding process what leads to improvement of the entire circuit work efficiency through decreasing the process energy consumption and enhancing the product size reduction.
