Cortez Hills Project Reaches Completion
The Cortez Hills project in Nevada, owned by Barrick Gold USA, has achieved completion and acceptance by Barrick Gold.
ThyssenKrupp Robins was selected to design and supply a complete new 9 mile long belt conveyor system for transporting 1,000 stph of gold ore from the new Cortez Hills mine to an existing Heap Leach facility.
The ThyssenKrupp Robins scope of supply included a belt feeder and five conveyors that make up the conveying system. The 90 ft long variable speed belt feeder will transfer primary crushed ore to the first of the 5 conveyors.
The most complex conveyor of the system is the 38,000 ft regenerative overland conveyor that runs at 900 fpm with a 2 mile long downhill section that drops 900 vertical feet. This is followed by a long radius horizontal curve section. A unique control system was developed to verify that the proper belt tension is achieved between the drives.
