An Energy Benchmarking Model for Mineral Comminution

July 10, 2016 | Energy Conservation

A method for determining the minimum practical energy for comminution was developed and is presented in this paper. An objective of the method was to determine experimentally the energy-breakage relationship for a wide size range in order to evaluate the energy performance of both crushing and grinding processes using one energy benchmarking value. Single-particle compression […]

Energy Benefits of Implementing Drill-to-Mill Strategies in Open-Pit Copper Mines

July 1, 2016 | Energy Conservation

Over the last 10 years the benefits of optimizing both blast designs and operation of crushing and grinding processes, also known as drill-to-mill optimization, have been shown at a number of mining operations. Significant improvements in production and revenue potential are typically associated with the successful implementation of drill-to-mill strategies. Less information is available on […]
