The grinding tests were run for different time intervals (1, 2, 4 and 8 min). After each interval, the whole mill charge was discharged and a representative sample taken for sieve analysis. Later, the material retained on the sieves were recombined with the rest of the mill discharge as feed for the next grinding interval.

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 ball mill with the help of a partial product ...
