Equipment to Recover Gold without Chemicals

This may be ‘entrapped in sulfides.’ A standard ball mill may grind your ore to 75 microns. Gravity Recoverable Gold (GRG) refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG (Gravity Recovery Gold) testing is available. The number 1 application for iCON i350 worldwide is Hard Rock.

Jan 01, 1991 The gold occurs as particles in the 10-60 micron size range, but some coarser, visible gold is present [8]. The ball mill discharge feeds the jig directly (i.e. with no intermediate cyclone). The jig concentrate contains 1000 g/t Au and recovers 40 to 45% of the total gold in the mill feed.

GRAVITY RECOVERY OF GOLD FROM WITHIN GRINDING
