The GRG (gravity recoverable gold) test is a widely accepted industry test used to determine the theoretical maximum amount of gold that can be recovered from a sample. It is also the most popular test performed in KRTC facilities.

This test is a multi stage test that utilizes the KC-MD 3 laboratory Knelson Concentrator with sequential grinding. A 30kg of sample crushed to -1.7mm (sample crushing can be arranged at an extra charge) is required to perform a GRG test.

The price of the GRG test includes all assays at an independent lab and a comprehensive metallurgical test report detailing testing results and analysis.
