Glencore Technology’s IsaMill chosen for Red Dog upgrade

Teck Resources has selected Glencore Technology’s M15,000 IsaMill for a mill upgrade project at the Red Dog zinc operations in Alaska, United States.

The solution is expected to increase the site’s average mill throughput by about 15 per cent over the current mine life.

Red Dog, which is north of the Arctic Circle and one of the world’s largest zinc mines, required grinding equipment that could be retrofitted within the confines of an existing modular mill layout, while providing sufficient power to achieve metallurgical targets.

The M15,000 IsaMill will be operating in a quaternary milling duty treating lead pre float tail prior to lead flotation and will reduce particles from 150 to 60 microns. The M15,000 is the newest addition to the IsaMill range, and uses a slightly longer and wider size to increase capacity more than the next available size, the M10,000.

Glencore Technology general manager Paul Telford said: “The remoteness of the site means high energy efficiency and low installation cost is needed, which makes the horizontal IsaMill with its high energy efficiency and small footprint ideal for this application to reduce cost while achieving the grinding duty.

“We have had a long relationship with the Red Dog site since 2007, having provided a Jameson Cell for their prefloat cleaning circuit, and two M5000 IsaMills for several duties in their zinc circuit. We are proud to continue the relationship with the new M15,000 IsaMill being installed at their site.”
