The Global Mining Standards and Guidelines Group (GSMG) would like to announce that it will be hosting an interactive workshop, “Evaluating Comminution Energy Efficiency,” at the upcoming World Gold 2015 Conference. All interested parties are invited and encouraged to attend this free pre-conference workshop. The workshop will take place on September 28th, 2015 at the Misty Hills Conference Centre in Johannesburg, South Africa.

Evaluating Comminution Energy Efficiency
This is a course for metallurgical professionals about the sampling and evaluation of energy efficiencies for typical mining comminution circuits. The methods and guidelines presented are applicable to AG (autogenous grinding), SAG (semi-autogenous grinding), SABC (semi-autogenous, pebble crusher and ball mill) and SAB (semi-autogenous and ball mill) circuits.
As mining companies increasingly focus on cost reduction and energy efficiency improvements, within a challenging operating environment, it is of substantial value to focus on the costs and energy efficiency associated with comminution circuits. As such, there is a need for mining professionals to be able to quickly and easily assess opportunities for improvement within their comminution circuits. These improvements aim to reduce both: unit operating costs and unit energy consumption. A reduction in the aforementioned metrics improves both the financial performance and unit emissions of the circuit.
Comminution (size reduction, primarily through crushing and grinding) is a major cost centre within most mines. For mining facilities comminution is generally responsible for a substantial share of energy usage at a mine site. Placed against other contributing factors, such as (1) diminishing run of mine ore feed grades; (2) rising energy costs; and (3) a continued focus on greenhouse gas emissions, there is a need for innovative tools, solutions and support.
This course provides a comprehensive introduction to all aspects of assessing comminution energy efficiency within a typical mining comminution circuit, including:
• Best practice circuit sampling
• Efficiency evaluation using the Bond method
• Efficiency evaluation using the Morrell method
• Planning your path forward to better performance
The course comprises an interactive workshop session, covering each of the each of the major sections described above, plus supporting figures, tables and references, appendices and interactive reviews that confirm your achievement of the learning objectives. The total duration of the course is approximately 6 hours.
The GMSG Industrial Comminution Efficiency (ICE) Working Group aims to standardize metrics and methodologies for the evaluation, benchmarking, and improvement of industrial comminution efficiency within the hard rock mining sector. The guidelines presented arise from the collaborative work of internationally recognized consultants, mining vendors and mining operators.
