thyssenkrupp to deliver material handling system with gearless conveyor for Anglo American’s new copper mine in Peru

February 19, 2019

One of the world’s largest copper reserves will soon be accessed with the help of high-capacity overland conveyors from thyssenkrupp. The Industrial Solutions business area recently won a contract to supply a material handling system for Anglo American’s new Quellaveco copper mine in the Moquegua region of Peru.

thyssenkrupp will supply a 4,700-m (15,420-ft) long, 1,830-mm (72-in.) wide overland conveyor featuring dual 5.5 MW gearless drives operating at a design tonnage of nearly 10 kt/h (11,000 stph). The scope of supply also includes the complete material handling system for the concentration plant including 203 mm (8 in.) plant conveyors and 11 belt feeders. First production from the new mine is expected in 2022. 

Due to their proven track record of high reliability and efficient use of energy, gearless drives were selected to power the new overland conveyor. The elimination of a whole series of mechanical and electrical components increases the reliability and improves the efficiency of the overall system by three to four percent. The maintenance requirements of gearless drives are also substantially lower compared to other drive systems.

Torsten Gerlach, chief executive officer of the Mining Technologies business unit said, “This order again shows how gearless conveyor systems meet today’s demand for ever more efficient mining solutions and increased safety requirements. It is the seventh overland conveyor project of this magnitude utilizing gearless drives that has been awarded to us since 2010. Together with our partner Siemens, we have managed to become one of the world leaders in bringing this technology to the market.”

The new conveyor system will initially move 115 kt/d (127,500 stpd) of primary crushed ore from the pit to the stockpile adjacent to the copper concentrator. Quellaveco contains approximately 6.8 Mt (7.5 million st) of copper in ore reserves – enough to wire 80 million homes or to equip 90 million electric vehicles. Vast sections of the overland conveyor will traverse from one valley to another through a 3.2-km (2-mile) long tunnel. After exiting the tunnel, the conveyor will pass over hilly terrain before terminating at the stockpile. The stacker will feature a structure designed to replace the discharge pulley without the need to clear out the stockpile for crane access. thyssenkrupp has designed similar systems for both the Antapaccay and Las Bambas mines in Peru.
