Terra Nova Technologies (TNT) has announced that it has been awarded the supply of two 72 in (1,829 mm) wide by 250 ft (76 m) long Super Portable® mobile stacking conveyors by a top tier mining customer for a large copper mine in the USA. This equipment will expand an existing Super Portable heap leach stacking system which has been in operation since 2014. TNT Super Portable systems have been successfully used in high capacity multi-lift heap leach, dry tails and waste stacking applications up to 10,000 t/h.

The company states: “Super Portable System Technology is the result of years of innovative design work that is revolutionising heap leach stacking systems. Innovative, yet simple, this technology reduces scheduled down time, and increases system mobility and operational flexibility. The portable conveyors are truly mobile, being equipped with all-track propulsion and on-board generators. This allows rapid redeployment of the conveyors from cell to cell and lift to lift. TNT’s Super Portable system includes several other subtle design features that show our knowledge of heap leach and other stacking operations, and an appreciation for the client’s operating costs.”
