In order to explore the influence of ultrafine grinding using high-pressure grinding roller (HPGR) on the separation performance of copper-bearing iron ore, mineral separation tests were carried out for HPGR milled ore. The results show that HPGR products are usually smaller and more uniform in size compared to jaw crushing products. Furthermore, obvious grain boundary cracks in HPGR products can be observed. Based on the comparison with jaw crushed ore, a test on magnetic separation of HPGR milled ore for tailings discarding led to the obtained product with iron grade up by 0.4 percentage points and iron recovery down by 0.8 percentage points, while both copper grade and recovery up by 0.01 and 2.11 percentage points respectively. A flotation test resulted in the roughing concentrate with copper grade and recovery up by 0.21 percentage points and 1.84 percentage points, respectively. The following magnetic separation test of the obtained roughing tailings led to the final iron concentrate with grade and recovery up by 1.11 and 2.45 percentage points, respectively. It is concluded that compared with jaw crushing, HPGR grinding is more conducive to improving copper grade and recovery of iron concentrate.
