Swedish mining company Boliden has set a new production record at its Aitik copper mine. On July 14, 2013, 144 912 tons of ore passed through the plant, and thanks to a steadily increasing average production, July 2013 ended up being Aitik‘s most productive month to date with 3.5 million tons of ore. The mine is now operating at an annual rate of 45 million tons. Boliden‘s official target for 2013 is to produce 38 million tons of ore in Aitik. The new record marks a significant milestone in the collaboration between Metso and Boliden. Metso is responsible for all maintenance in the grinding mill circuit in the Aitik concentrator, and has supplied most of the equipment, including two gigantic, 11.6 m by 13.7 m AG grinding mills (Fig.). In September 2012, the two companies signed a three-year extension of their comprehensive Life Cycle Services contract. The contract is cost-per-ton based, meaning that Metso gets paid based on Aitik‘s production. The higher the output, the more both parties benefit.
