The Russian Copper Co. (RCC) contracted Metso to supply SAG and ball mill linings for the former’s Tominsky processing plant. The deal complements two earlier mill lining contracts for RCC’s Mikheevsky processing plant, signed in December 2019, Metso reported.

The contracts cover roughly one year’s worth of mill lining needs and are part of RCC’s large-scale mill lining project.

First shipments were calendared for March 2020. The contracts, combined, are booked at $26 million.

RCC said it invests in the best available technologies and so went with Metso. “This ensures superior operational performance of our enterprises, as well as the safety of technological processes for human health and the environment,” RCC President Vsevolod Levin said.

RCC is one of the biggest copper producers in Russia.

Separately, Metso reported further investments at its Mesa repair facility in Arizona with the goal of optimizing safety and broadening service capabilities. The facility offers repairs and field services while supporting Metso’s Life Cycle Services contracts.

Metso said the Mesa repair facility has seen steady growth since it opened in 2015, with 2019 setting a record for safety performance, revenue and profitability.

To offer a more complete service to customers on large rebuilds, the Mesa facility recently installed a state-of-the-art stress-relief oven. It will improve quality control as well as accelerate the turnaround times for clients, the company reported.

Mesa also invested in other equipment to support the repair of mining screens, LIMS (Wet Low Intensity Magnetic Separator) drums and babbitted bearings for mills.

A screen test stand was manufactured and was calendared for completion at the end of March. The stand will allow each screen that is rebuilt at Mesa to be test-run before being sent back into the field, which should reduce the potential for issues during installation and startup.

Equipment needed to repair LIMS drums was also put in place last year, and has seen a steady inflow of repairs coming from mines in the Iron Range, Metso reported.

In the future, the facility aims to further grow its portfolio of value-added services to improve productivity and reduce operational costs for its clients in both the mining and aggregates sectors.
