ABB ectrical equipment for
new copper plant in Mongolia

ABB has won an order for a major electrical equipment package from Mongolyn Alt Corporation (MAK) for its greenfield copper and molybdenum project Tsagaan Suvarga (Fig.). The site is located in the Eastern Gobi Desert in Mongolia, approximately 560 km south of the capital, Ulaanbaatar. Established in 1993, Mongolyn Alt Corporation is one of Mongolia’s largest national mining companies with three open-pit coal mines in operation. With a targeted production volume of 40 000 t of copper per day, the Tsagaan Suvarga project is expected to become the third largest copper mine in Mongolia.

Integrated into pre-fabricated containerized E-houses, ABB’s scope of supply includes 22/6.6 kV switchgears, DC power supply, uninterrupted power supply, transformers, 400 V motor control centers, variable-speed drives, variable-speed multi drives as well as a power management system based on the state-of-the-art process control System 800 x A and IEC 61850. The incorporation of the equipment into pre-fabricated E-houses reduces the erection work on site and thus optimizes the overall time schedule. Furthermore, the solutions are proven for stable operation under extreme variations in temperatures from -35 to +40 °C. Deliveries are scheduled to take place from December 2013 to May 2014 and first plant start-up is planned for September 2014.
