This circuit model uses the Bond/Barratt models for SAB and SABC circuits except that the work index values simulated come from a Normal distribution that is defined by synthetic test samples loaded into the Testwork database. The parameters loaded into the database to not represent actual laboratory test results, but the inputs to the random number generator.
The laboratory test parameters are used to encode Monte Carlo statistics according to this recipe:
- Bond ball mill work index is simulated as an independent variable
- The wibm field encodes the mean of the distribution
- the gpr field encodes the standard deviation of the distribution
- Bond rod mill work index is simulated as dependent on the ball mill work index
- the WiRM mean comes from linear relationship WiRM = Coeff * WiBM + Const
- the wirm field encodes the Coeff of the WiRM/WiBM relationship
- the p80 field encodes the Const of the WiRM/WiBM relationship
- the gpr field encodes the standard deviation of the rod mill work index
- Bond crushing work index is simulated as an independent variable
- The wic field encodes the mean of the distribution
- the stddev field encodes the standard deviation of the distribution
- Ore density is simulated as an independent variable and is encoded in the WiC table
- The max field encodes the mean of the distribution
- the min field encodes the standard deviation of the distribution
