Scope

Comminution circuits currently account for the highest energy usage in the mining industry. According to a report by the Coalition for Energy Efficient Comminution (CEEC), grinding and crushing ore is 53 per cent of an average mine site’s energy consumption.

The Industrial Comminution Efficiency (ICE) Working Group aims to standardize metrics and methodologies for the benchmarking of industrial comminution efficiency within the hard rock mining sector with the publication of three guidelines: Determining the Bond Efficiency of Industrial Grinding Circuits, Methods to Survey and Sample Grinding Circuits, and Morrell Method for Determining Comminution Circuit Specific Energy and Assessing Energy Utilization Efficiency of Existing Circuits.

The guidelines provide a user’s guide to implement common tools for hardness testing and data analysis for the creation of a best practises approach for increasing productivity and cost-efficiency through benchmarking.

Objective

To reduce both unit operating costs and unit energy consumption, by applying best practice comminution circuit analysis techniques/methods through three published guidelines.
