  • Gravity Recoverable Gold (GRG) Test

    Oct 08, 2015 · A Gravity Recoverable Gold Test (GRG) value of an ore sample provides an indication of the amenability of the ore sample to gravity concentration. The GRG testing scheme is based on progressive particle size reduction, which allows recovery of gold as liberated while minimizing over grinding.

  • 10 Do's and Don'ts of Gold Gravity Recovery

    Gold gravity recovery should then target most gold particles rather than the exceptionally coarse particles. A GRG test is available to yield the information needed for gravity circuit design and performance prediction (Woodcock and Laplante, 1993). For most applications where the impact of gravity is “modest”, a single test is sufficient.

  • Advantages Of Using Gravity Concentration For Gold Recovery

    Using gravity concentrators can help mitigate the nugget effect by extracting the gravity recoverable gold (if there is any), leaving a homogeneously graded material ready for downstream processing. If there isn’t any gravity recoverable gold, you can be sure that you’ll get the best recovery from your chemical processes.
