The GRG Test (Ore Characterization) The gravity-recoverable-gold content of an ore, as obtained via a GRG test, provides a quantitative theoretical limit of gold that can be recovered using a BCC. The test itself consists of a sequential liberation via grinding followed by gravity concentration using a lab scale BCC (see Figure 1).

ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,
