The mining company Minera Media Luna, S.A. de C.V. (MML), which
is a wholly owned subsidiary of Torex Gold Resources, Inc., operates
the gold mine El Limón-Guajes roughly 180 km to the southwest of
Mexico City. When it came to transporting the extracted ore, MML
decided on the proven RopeCon ® from Doppelmayr Transport Technology.
The open-pit mine El Limón is located on a steep ridge some
400 m above the central processing facility. The rope span between
the loading station and the only tower is 1,200 m. The RopeCon ® used
for the El Limón project generates approximately 1 MW of "green" energy
via the braking system, which reduces the overall running costs.
The avoidance of dust and noise emissions is another factor in favor
of the RopeCon ® system. In addition, the automatic transport system,
which can be integrated into the mine’s central control system,
increases the safety of operations. Over the entire life of the mine, of
roughly ten years, the RopeCon ® will carry 1,000 tons of ore per hour.
