Since the year 2005, a RopeCon® system by Doppelmayr Transport Technology GmbH, Austria, has been transporting inert material along a long-stretched valley at the Tüfentobel landfill site, which will eventually be backfilled. The belt is being extended in several stages. It discharges the material onto a debris cone directly where it is to be used. Finally in March 2016, a novel concept was implemented which has further increased the flexibility of RopeCon®.
Doppelmayr Transport Technology GmbH develops, plans and builds material transport systems for a wide range of applications.
Doppelmayr Transport Technology is a 100 percent subsidiary of the Doppelmayr group. Doppelmayr, the pioneer and technology leader in ropeway engineering, has built more than 14,700 passenger and material transport systems in 90 countries. Customers from all over the world rely on state-of-the-art engineering from Doppelmayr to transport their bulk material or unit loads – from zinc concentrate in Greenland to automobiles in Slovakia to bauxite in Jamaica.
To connect the El Limón gold ore pit with the processing plant it was necessary to overcome an altitude difference of approx. 400m in steep terrain. Minera Media Luna, S.A. de C.V. (MML), 100% owned subsidiary of Torex Gold Resources Inc., opted for the RopeCon® by Doppelmayr Transport Technology as a means of transport. Along with other aspects, safety and environment were key considerations in prompting the decision. The system transports 1,000 metric tons of gold ore per hour into the valley over a distance of 1.3km.
