Antapaccay Copper Mine

Antapaccay Copper Mine

Located at 4,200 meters above sea level in the south of Peru, Antapaccay mine began production in the fourth quarter of 2012. The plant has an estimated process capacity of 70,000 tonnes per day and, in the initial years of its more than 20-year projected mine life, is projected to produce an initial 160,000 tonnes of copper in concentrate per year.

The Antapaccay open-pit mine and processing operation are located approximately ten kilometers from former Xstrata’s Tintaya mine. Antapaccay is replacing mining operations at the Tintaya mine following the end of its mine life on the first quarter 2013. The exhausted Tintaya pit is used to store mine tailings from Antapaccay.

Commissioning of two synchronous condensers and harmonic filters.

Scope of supply included harmonic filters and controller, two brushless synchronous condenser systems comprised of 20-megavolt ampere synchronous motors, distribution transformers, frequency converters, excitation and protection panels as well as chiller systems.

ABB’s synchronous condensers will ensure accurate and dynamic power factor compensation for safe and reliable mine operation at this remote location. By integrating synchronous condensers and harmonic filters the harmonics are mitigated and short circuit levels improved, thus optimizing Antapaccay’s productivity and energy efficiency.
