Benchmarking: Bond/Barratt Circuit Specific Energy Consumption - Meadowbank
- Muteb, P. & Allaire, J., Meadowbank Mine Process Plant Throughput Increase, Proceedings of the Canadian Mineral Processors Annual General Meeting, Ottawa, Canada, January 2013.
Paper describes a "sick" SAG mill and the changes made to "bring it to health". The "healthy" mill conditions benchmark as follows:
- Actual SAG/ball motor powers (at shell): 3,168 kW / 4,105 kW
- Actual daily average throughput: 500 tonnes/hour
- Predicted SAG/ball motor powers (at shell): 3,096 kW / 4,182 kW
- Predicted nominal throughput: 500 tonnes/hour (0% difference)
