Metso celebrates Copper Mine’s 100 million tons of crushed ore
Metso and Freeport-McMoRan celebrated an impressive milestone as the new HRC™3000, the world’s largest operating high-pressure grinding roll, at the Metcalf Concentrator crushed its 100,000,000th short ton of ore.
Reaching one hundred million short tons of crushed ore is a significant milestone for the world’s largest operating high-pressure grinding roll.
Due to its capacity, the HRC™3000 reached this milestone in less than three years. The HRC™3000 began operating in May 2014 at the Metcalf Concentrator at Freeport-McMoRan’s copper mine in Morenci, Arizona, USA.
Morenci is an open-pit copper mining complex that has been in continuous operation since 1939.
The HRC™3000 is the largest unit of its kind in the world, allowing for fewer lines of equipment which reduces the amount of ancillary equipment. The HRC™3000 is the first full scale high-pressure grinding roll to incorporate revolutionary design features such as the flanged tire design and the patented Arch-frame. Metso’s solution has provided the Morenci mine with several benefits, including an estimated 13.5% increase in energy efficiency over traditional high-pressure grinding rolls based on pilot scale testing.
