Beneficiation of a Low Grade Lead Ore by Gravity Pre ...

This study is to investigate the beneficiating possibility of a low grade lead ore in Yunnan by current mineral processing technology. A low grade lead ore sample assaying 1.14%Pb and 5.72g/t Ag was used in tests. In the experiment, gravity pre-concentration to discard the tailings and the effects of grinding fineness, types and dosages of reagents in roughing were investigated.

GRAVITY RECOVERY OF GOLD FROM WITHIN GRINDING

2019-10-1  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).
