Knelson Gravity GradeTest (GGT)
The GGT is a derivative of the industry standard Gravity Recoverable Gold (GRG) test. This test utlilizes enhanced gravitational forces combined with patented Knelson technology to provide a comprehensive grade estimation for the given test sample. With this test, sample head grades can be precisely measured by alleviating the nugget effect associated with sub-sampling. Knelson's Gravity Grade Test is a great tool for those involved in resource estimation of gold where high confidence in reported results is desired.
Test Description
Sample is processed in its entirety
Free gold is recovered with high efficiency in a small concentrate mass and fire assayed to extinction to account for all gold recovered
Test tailings can be sub-sampled and assayed with confidence because any remaining gold is finely desseminated
Fire assay results from the two streams are combined in a metallurgical balance to provide overall sample grade
Benefits
- Improve confidence in reported results
- Maximize gold resource value
- Minimize nugget effect
- Ability to analyze large samples
