The gravityrecoverablegold 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
washing machine Gravity Gold Processing Line Gravity separation process is the use of mineral density and particle size differences with the help of the dielectric fluid and all kinds of mechanical force combined to cause appropriate loose layer and separation conditions in order to gain the technological process of different density
This configuration can realize the recovery of coarse gold from the ore by Knelson Concentrator directly and maximize the recovery rate of gravity separation Gravity tailing is pumped to spiral classifier for classification it is better to use overflow ball mill grinding and install reverse winch screen at the discharging end of ball
The GRG test is used to determine the theoretical maximum amount of gold that can be recovered from a sample The testing scheme consists of three sequential liberation and recovery stages the progressive size reduction allowing for the determination of the precious metal recovery as liberated without overgrinding and smearing coarse precious metal particles A Gravity Recoverable Gold Test
