Rio Tinto has chosen CiDRA Minerals
Processing’s flow monitoring systems as its preferred technology for use on
slurry lines at Oyu Tolgoi. CiDRA will instrument 30 lines at the new
concentrator, where the SONARtrac systems will provide increased
accuracy and reduced maintenance costs.

Construction of the mine is
progressing ahead of schedule with first production now forecast to commence in
late 2012.
