The crushed ore is then hoisted to the surface and stored in crude ore bins, with a capacity of 60,000 tonnes. A conveyor moves ore from these bins to another crusher, where it is reduced to about 10 mm, and passed to fine ore bins. The ore then goes to a rod-and ball crusher for fine grinding, and is pumped to a floatation process, which ...
Newcrest deploys Microsoft cloud, AI and IoT tech at Cadia
The challenge facing Newcrest at Cadia was managing the levels in the underground crushed ore bins. If the bins overfill, they have to be manually emptied introducing lengthy and expensive production delays.
