PLANT ENGINEERING JANUARY 2019 • E&MJ 25 stages, supporting a company-wide focus on optimization. Giblett has 25 years' experience in operations, project development and cor- porate roles, predominantly with major gold mining companies. For the past 12 years he has worked for Newmont's Tech- nical Services group. In his current role he provides subject matter expertise in comminution to the company's operations and projects around the world. Giblett has been involved with site optimization stud- ies at operations in Ghana, Peru, North America, Indonesia and Australia. His role also incorporates identifying emerging technologies and best practices in com- minution around the world and incorpo- rating these into Newmont's operations. Hart has 29 years' operational and design experience, primarily in gold and base metals processing. He spent six years with Boddington during the design, commissioning and ramp-up of the oper- ation, culminating in just over 12 months as the Processing Manager. In his current role of Principal Advisor Processing, he has worked closely with the Tanami and KCGM operations, contributing to plant improvement projects in comminution, metal recovery and cost reductions. A significant component his current role is to work closely with the site-based metal- lurgical and processing teams on longer term strategies as well as research and development opportunities. The Approach Newmont's strategic approach to plant optimization and design incorporates the Full Potential program and the efforts of the corporate Technical Services teams to identify and rank emerging technol- ogies and industry developments to im- plement and promote the best practices across its operations. "This program has been in place for a number of years and is very effective. At the core of the program are subject matter experts and processes to screen, evaluate and rank any number of site op- timisation initiatives," Giblett said. "The Full Potential program gives sites the mechanisms to get the projects prioritised, resourced and implemented. A lot of this is due to the rigor the pro- gram puts on defining the value that will be created by the project. Value creation is a key guiding philosophy of the Tech- nical Services team. Committed to documenting and sharing Newmont's comminution improvements, Aidan Giblett, internal comminution specialist, and Steven Hart, Newmont Australia's Principal Advisor Processing, presented a paper, 'Grinding Circuit Prac- tices at Newmont,' which they presented at the AusIMM's Mill Operators' Confer- ence at Perth in 2016. Giblett and Hart were awarded the 2017 CEEC Medal for the operations category for their efforts. The CEEC Medal is a prestigious an- nual award that recognizes the most outstanding published papers, articles or case studies that profile energy-efficient comminution and mineral processing strategies. Nominations are reviewed by the CEEC Medal Evaluation Committee for applicability, supporting research and documentation, prospective impact, potential energy savings, and presenta- tion style. Established by the industry, for the in- dustry, the Coalition for Energy Efficient Comminution (CEEC) is an internation- al, not-for-profit company committed to sharing energy efficient mining processes to help lower costs, increase productivity and improve shareholder value. To drive this mission, CEEC has established a col- laborative global network of mining lead- ers, technical experts and researchers. CEEC CEO Alison Keogh said in 2017 the coalition received a record number of nominations and the competition was ex- traordinarily high. "Nine of the 18 papers put forward for the CEEC Medal were potential win- ners, demonstrating that many individ- uals and organizations are striving for improvements and advances in miner- als processing and comminution. That's good for the industry. CEEC is proud to share this work and inspire miners and researchers around the world to help drive incremental and transformative change," she said. "Aidan and Steven's paper highlight- ed Newmont's challenges and approach to improving grinding practices across its 12 operations around the world. "An exceptional contribution to the global mining industry's body of knowl- edge, the paper provides practical solu- tions and clear guidance on reducing risks and improving performance." Giblett said Newmont had significant experiences in plant optimization and design. He and his colleagues wanted to share the insights from their diverse pro- ject experience and their paper was one means of doing that. "One of the things the industry doesn't always do as well as we would like is doc- umenting and sharing its experiences, so we wanted to do that — celebrate some successes, promote and contribute pos- itively to conversations around effective comminution circuit selection, design and operation," he said. Giblett said although some of the ini- tiatives highlighted in the paper had short delivery times, the more significant proj- ects took between two and five years from concept to execution. "There is often some time required to effectively communicate the concept and get enough buy-in to progress the project with real purpose," he said. "A lot of times you might be imple- menting something that was raised or identified some years back, but never got off the ground. Sometimes you need to be patient and wait for the right alignment of business priorities and personalities to get some real traction." Applications for 2019 CEEC Medal are now open.
