As noted earlier, copper minerals and gold tend to concentrate in the finer size fraction in the SAG mill trommel undersize. If the metal distribution is compared on a size-by-size basis, it was found that SAG mill trommel undersize sample contained richer copper content than the cyclone underflow in the fine size fractions.

A gold and copper mine in South East Asia was experiencing a range of challenges with its SAG mill that were hitting productivity. Facing a significant increase in ore hardness that would have exacerbated the problems, the mine turned to us to provide a solution for a safer and more productive grinding operation.

The results show that the mineralized material is of moderate competency and hardness and is amenable to grinding in a conventional SAG mill / ball mill circuit. Flotation testing indicated that 85.6% of the copper and 60.8% of the gold are recovered to the final concentrate, which results in a concentrate grade of 30% copper and 21 g/t gold.

With the additional SAG mill, the milling capacity will be approximately 240,000 tonnes per day, the company claimed. President of Fluor's Mining and Metals business, Tony Morgan, said the new mill would build on "other major projects" Fluor has built at Grasberg since the 1980s.

"Gold production was 27% lower than the prior period mainly driven by lower mill throughput rates at Cadia, Lihir and Telfer. As foreshadowed in the June 2021 quarterly report, Cadia's mill capacity was limited by the replacement and upgrade of the SAG mill motor resulting in lower gold production during the period.
