Gravity Recoverable Gold GRG Test
The gold head grade of the sample was calculated to be 1 1 g tonne with a final gravity gold tailings grade of 0 6 g tonne The grind P80 of the final stage was 76 181 m Based on project P420B by AMIRA the concentrate gold grain sizes corresponding P20 P50 and P80 values for the sample are 55 122 and 218 respectively thus classifying the gold recovered as coarse
