Las Bambas Copper Mine
Las Bambas is a joint venture project between the operator MMG (62.5%), a wholly owned subsidiary of Guoxin International Investment Co. Ltd (22.5%) and CITIC Metal Co. Ltd (15.0%).
Las mine is located at Challhuahuacho, Apurímac Region, Peru. It is a open-pit mine located at altitude of about 4000 m. Las Bambas has significant mineral resources and ore reserves of copper, gold, silver and molybdenum and once in production is estimated to have a mine life in excess of 20 years. The mine is called as world-class Tier-1 copper asset. Production at the mine will start in 2015.

Formwork and Scaffolding for construction sites
Doka Perú SAC
The sheer scale of this construction project and of its various sub-projects means that huge quantities of formwork equipment are in service. Most of the works are being carried out using 4,500 m2 of framed formwork Framax Xlife and 500 m3 of load-bearing towers Staxo 100.
The ore breaking and crushing installations comprise outsize foundations, concrete blocks and steelwork, on which the machinery is stood. The high-performing framed formwork Framax Xlife system is ideal for large areas of this type and for high walls. The crane-jumped climbing formwork MF240 is being used for the massive walls of the crushing plants.
The 2 m to 2.5 m thick slabs, with steel inserts, necessitate the use of a stop-end formwork in the form of a single-sided wall. Doka is fulfilling these requirements with its dam formwork D22 system.

Gearless Mill Drive systems (GMDs)
Siemens
Siemens Drive Technologies Division has received an order from ThyssenKrupp Robins to supply the gearless drive system for the overland conveyor system in the Las Bambas copper mine in Peru.
The Siemens drive systems for each of the two overland conveyors (provided by ThyssenKrupp Robins) comprise two low-speed synchronous motors – each with a total power of 4,400 kilowatts – and the associated Sinamics SL150 cycloconverters.
This gearless drive solution has a number of advantages over the combination of high speed motor and gearbox drives usually used on conveyor systems. The size of the motor is not limited by the size of gearbox available, thus eliminating the necessity to install multi-motor drives.
