Metso Outotec and Boliden have signed an extension of their service contract for Boliden’s Aitik copper mine in Gällivare, Northern Sweden.
Megaliner™ mill liner
The 3+2-year extension of the Life-Cycle Services agreement covers the supply of mill lining, chute lining solutions, preventive maintenance of the grinding circuit and recycling of used wear parts. The value of the order will not be disclosed. The first part of the contract has been booked in Metso Outotec’s orders received in Q3, 2020.
The contract is a performance-based cost-per-ton agreement, in which Metso Outotec gets paid according to the output of the customer’s process. The goal is to ensure the availability of the grinding circuit and to maximize valuable production time, striving for a common goal that benefits both parties.
Long partnership developing responsible mining business
Metso Outotec and Boliden have cooperated since the 1960s. Throughout the decades, the collaboration has evolved to meet new emerging needs, while continuing to improve uptime and annual production.
Safety is Boliden’s top priority and enhancing it is also embedded in the scope of the new contract. Metso Outotec will provide solutions that simultaneously cut maintenance time and increase the wear life of parts even further. The new contract also focuses more on the management of worn wear parts, because Metso Outotec will develop capabilities to recycle and dispose them more sustainably. The AG mills in Aitik will continue to use Metso Outotec’s innovative Megaliner(TM) mill lining.
Megaliner speeds up maintenance
Megaliner helps to maximize the availability of large mills by utilizing an innovative design that speeds up liner replacement. The larger-than-average liners mean that fewer individual pieces are needed. Megaliner also has fewer attachment points compared with conventional liners, further improving installation and removal time. It also improves worker safety during maintenance, because the liners are bolted into position from outside the mill.
The pebble mills and two regrind mills will be lined with rubber and Poly-Met mill linings.
Aitik is one of the largest copper mines in Europe. In 2019, the mine produced close to 41 kt of copper, employing nearly 800 people.
