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 …

HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific ...

They were introduced in 1993 at Buzzi Unicem's Trino plant in Italy with the purpose of reducing energy costs. Details of the operating principle of Horomill ® as compared to HPGR and vertical roller mills are given by Cordonnier (1994) and Buzzi (1997).The energy saving of this mill is claimed to be similar to that of HPGR and …

The high pressure of HPGR's "bed-breakage" creates micro-cracks in the ore, promoting improved mineral recovery at coarser size fractions. This means less leaching acid is required and percolation periods are shortened, reducing costs and maximising recovery in less time. In the diamond industry, the HPGR acts as a selective grinder ...
