Why gold mines are adopting HPGRs to increase

For gold mines using carboninleach (CIL) processes for recovery, we’ve found the best results are achieved with a HPGR performing tertiary grinding before a ball mill further reduces the product In this role, the HPGR significantly uplifts the capacityPlants with gold treatment or with significant gravity gold production may include a smelting stage in order to get a gold ingot Falcon Concentrator; This equipment is a fluidized bed spinning bowl gravity concentrator It is has been designed primarily for gold recovery from grindingGold Extraction & Recovery ProcessesGRINDING FOR GOLD Tough, carbonhardened grinding rods made from WRSteel® are helping a gold production plant in southern Finland maintain reliability and low costs in the critical grinding process In today’s gold mining industry, producing even the tiniest amount of gold requires the mining and processing of enormous amounts of oreCASE STORY · WRSTEEL GRINDING RODS · DRAGON
