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 …

Grinding is usually performed in a ball mill for the purpose of reducing the ore to sufficient fineness that the gold particles may be exposed to the dissolving action of the cyanide solution. This dissolving action may begin either in the ball mill or in the agitators. In the former case, the grinding is done in cyanide solution.
