SGS has developed a simple methodology that is based on the 0.25 m LABWAL HPGR from Polysius, which has a sample top size of 12.5 mm. Several HPGR tests are performed to assess the effect of operating pressure and moisture content on the performance of the HPGR and the power input to the unit is recorded.
The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through ...
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
