How HPGR improves gold recovery There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we’ve found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the use of a
