An overview of the HPGR and fine grinding technologies to characterize ore grindability

SGS's FRANÇOIS-OLIVIER VERRET presented the following summary on HPGR at the Quebec Mining meeting in November.

Several grindability tests were developed over the years to design grinding circuits or optimize existing operations. Each test has its own strengths and weak- nesses and purposes. It is imperative to select the proper test procedure(s) to meet project deliverables and minimize the risk of a project.

This presentation summarises the requirements and deliverables of selected bench-scale test procedures, namely the HPGR and fine grinding, applications and presents examples of test results.
