    This case study presents Iluka Resources Limited’s successful adoption of the Energy-Mass-Balance (EMB) as the core method of energy analysis in its Synthetic Rutile facility in Iluka’s South West Operations, Western Australia. It discusses key aspects of Iluka’s experience, such as the EMB modelling approach, results achieved, lessons learned and the role the EMB will play in Iluka’s future energy improvement initiatives. This case study was developed as part of the Energy Efficiency Opportunities program.

  • Case study: Barrick Gold Corporation - Improving Energy Efficiency in Barrick Grinding Circuits 2011
    • Coalition for Eco-Efficient Comminution
    • Webpage

    Barrick has reduced comminution energy on 3 mine sites by a total of 5.3% reducing energy costs by $5.2 million per annum. This has been achieved through a variety of energy efficiency strategies including optimising feed size in crushing and grinding circuits.

  • Case study: Xstrata Coal NSW 2007 (Opens in a new window)

    Xstrata Coal signed up as a trial company for the Australian Government’s Energy Efficiency Opportunities program in 2005. They conducted energy efficiency opportunities assessments at eight mines in NSW which resulted in the development of a series of action plans which included 47 cost-effective projects to be implemented immediately, and additional projects which required more detailed evaluation. Direct benefits have been quantified for 32 projects by January 2007 which achieve energy savings of 13 686 GJ per annum.

  • Case study: Thiess’ Australian Mining Business Unit 2009 (Opens in a new window)

    Thiess’ Australian Mining business unit has, through effective use of the Energy Efficiency Opportunities (EEO) Assessment Framework, found new efficiencies and dollar savings. The projects being implemented are payload management, automating mobile lighting equipment, plant idle-time management, and turbo idle-down time. Thiess estimates that these projects will deliver energy savings of 150,800 GJ/annum, 3.9 million litres of diesel fuel and $3.7 million with a simple payback period of less than two years. These projects will yield other business benefits, including: improved operational efficiency, reduced maintenance costs, and a reduction in the number of vehicles required. This case study was developed as part of the Energy Efficiency Opportunities program.
