Copper Mountain Mining announces installation of DFRs

This represents the first stage of its mill expansion project which will bring plant capacity to 45 000 tpd from 40 000 tpd. The installation of the DFRs increases the efficiency and the capacity of the current cleaner circuit, which is expected to increase copper concentrate grade from approximately 25% to 28%, resulting in lower concentrate transportation, smelting and refining costs.

“We are pleased that the installation of the DFRs was completed on schedule and on budget,” commented Gil Clausen, Copper Mountain’s President and CEO. “The DFRs have been commissioned and turned over to operations. This is a testament to the great work of our operating and projects team. The DFRs are a low capital, high return project and we are already seeing improved concentrate grades. The next stage for the mill expansion project is the installation of the third ball mill. We have the ability to rapidly restart this stage as we have maintained long lead time expenditures and we also have the flexibility to accelerate the project as necessary. With the installation of the third ball mill, we expect production to increase by 15 to 18% as a result of higher throughput and improved recoveries.”
