Ultra fine grinding of silver plant tailings of refractory ore …
Ultra fine grinding of the plant tailings of a refractory silver ore was studied using a laboratory type vertical stirred media mill. Preliminary tests confirmed that ultra fine grinding substantially improves the extraction of silver from the tailings in cyanide leaching (i.e. 36% Ag extraction rate from the as-received tailings with d 80 of 100 μm, c.f. 84% …

Why gold mines are adopting HPGRs to increase production …
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 …
