TNT portable conveying and stacking system being installed at Nordgold Gross

The overland conveying, portable conveying and stacking equipment from Terra Nova Technologies (TNT) is now being installed on site at Nordgold’s Gross all-season open-pit heap leach project, located in southwestern Yakutia, Russia, 4 km east of the Neryungri mine. At full production, Gross is expected to mine and process 12 Mt of ore, producing over 200,00 oz/y of gold for 17 years.

TNT’s contract was for the design and supply of five overland conveyors, two mobile trippers, an emergency bypass stacker, reclaim hoppers and three mobile stacking/reclaim systems. The mobile systems will support on-off heap leach stacking, reclaiming and tailings stacking, with a bypass stockpile and reclaim system.

The network of five 1,200 mm overland conveyors will feed the three mobile systems, which will comprise a total of forty-two 1,200mm mobile conveyors. These include thirty-two 38 m “grasshopper” style portable conveyors, two 20 m short portables, two 29 m horizontal feed conveyors, two 43 m horizontal conveyors, two 55 m radial stackers and two mobile crossover conveyors. This is the the second system supplied by TNT for Nordgold.
