Abstract/Summary The Cadia Mine again leads process design with the first truly hybrid HPGR-SAG circuit upgrading the circuit that had the world’s first forty foot SAG Mill. The hybrid approach addresses the risk of shifting to block cave with higher throughput, of higher competence, and uncertain ROM size but expected depletion of fines. During commissioning, materials handling and constantly rebalancing the circuit presented the main challenges, requiring a new maintenance schedule and operating philosophy. With the process now stabilised the plant has entered an optimisation phase to take advantage of the potential upside that the new circuit has to offer.
