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: 535 tonnes/hour (+6% difference)
