Figure 1 – PT Newmont Nusa Tenggara Batu Hijau Project Comminution Circuit The SAG Mill was designed with 13.4 MW of installed power for size reduction from a 175mm feed size down to 2 mm -10 mm of product size with given maximum ball charge of 13% by volumea (using 127 mm diameter grinding media).

The Batu Hijau is a large open pit porphyry copper/gold deposit mined using traditional truck and shovel techniques. The Batu Hijau operation is currently extracting Phase 6 ore utilizing a mining fleet of 111 trucks, six electric shovels and three excavators which are capable of moving an average of 815,000 tonnes of material per day.

The Batu Hijau SAG mill specific energy was a function of point load test and RQD. The point load test substitutes for Axb measurement in that relationship. The Batu Hijau ore is less fractured than the Constancia ore based on the average RQD data and

Advances in Comminution comes at a critical time. It focuses on the dilemma of needing to grind materials to ever-finer sizes while maintaining reasonable energy costs. The selection and sizing of stirred mills for regrinding and ultrafine grinding applications do not lend themselves to conventional methodologies; therefore, new approaches are being developed.

Understanding Mine to Mill is presented in five parts. Part A – Setting the Scene provides some definitions of Mine to Mill (M2M) and the historical background. A chronology of Mine to Mill developments is followed by brief descriptions of the very wide range of Mine to Mill applications which have been implemented over the last 15 years.

2 Batu Hijau Copper-Gold Mine Introduction On the tropical island of Sumbawa, located in a remote section of Indonesia, is the Batu Hijau gold-rich porphyry copper deposit. The Batu Hijau mine was the world's largest greenfield mining project when it was developed by PT Newmont Nusa Tenggara.

Operations including Newmont's Batu Hijau have retrofitted SAG screens to supplement trommels, while Newcrest built and commissioned a circuit screening trommel oversize at Ridgeway after the trommel-only circuit at Cadia resulted in difficulties with the pebble-crushing circuit (Goulsbra et al., 2003; Dunne et al., 2001; Hart et al., 2001).

Further increased efficiencies and cost savings include Batu Hijau in Indonesia, where a throughput decline was reversed and annual revenue increased by an estimated $150 million, while optimisation initiatives at one of Polyus Gold's sites led to an annual increase in revenue of over $30 million with the assistance of the SMC Test.
