Advances in Gravity Gold Technology
Gravity separation relies on different specific gravity of minerals and their relative motion under gravity and drag forces. This chapter describes units, circuits, and strategies that are used to recover gravity-recoverable gold (GRG) from very high-grade gold particles and from sulfidic particles with low-grade gold content.
