CEEC Medal winners inspire miners to add value and navigate to success
By Sandy Worden and Alison Keogh
Newmont Mining is achieving sustainable improvements in its comminution circuits by taking a strategic approach to plant optimization and design, and sharing leading grinding practices across its 11 gold mining operations in the USA, Australia, Peru, Ghana and Suriname. Business efficiency and production costs have been the main drivers for change in the company’s comminution practices and, through these initiatives, Newmont has been able to reduce its production costs. Examples include addressing power consumption at Ahafo in Ghana and reducing grinding media usage rates at operations like Twin Creeks (USA) and Tanami (Australia); boosting throughput and metal recoveries at Boddington; and increasing throughput at Kalgoorlie Consolidated Gold Mines (KCGM).
