Metso hydrocyclones head to gold mine in northern Canada

A gold mine in Nunavut will soon incorporate one hydrocyclone cluster with three MHC 250 hydrocyclones and a VTM 500 Vertimill grinding mill into its operation.

Metso sold the machines to Agnico Eagle for its Meliadine gold mine project. The Meliadine property covers more than 80 km of a greenstone belt, and is under development as an underground and open pit mine and mill operation. Meliadine, which is expected to start operation in 2019, is Agnico Eagle’s largest development project based on reserves and resources.

The delivery is scheduled for the first quarter of this year, and the equipment will be used for regrind application of gold ore.

“Our team carried out a thorough technology and total cost of ownership review for this special application,” said Daniel Seguin, engineering manager at Agnico Eagle. “The combination of the Vertimill 500 grinding mill and the MHC 250 hydrocyclones provides us with a total comminution solution. The remoteness of the Meliadine site placed added value in the low media consumption associated with the Metso VTM technology and its ability to maintain a stable product across a significant range of feed variations.”

MHC hydrocyclone is part of Metso’s process equipment portfolio for the mining industry covering classification, beneficiation and dewatering processes.

The MHC series includes seven sizes, ranging from 100 to 800 millimeters in diameter and are available both individually and in clusters. Metso’s new MHC Series hydrocyclones deliver a high unit capacity and separation efficiency for a wide range of classification duties.

“We are grateful for Agnico Eagle’s confidence in Metso,” said Frank Cacchione, Metso’s vice president of Minerals Processing Solutions Sales for the United States and Canada. “We are more committed than ever to continue developing and packaging our solutions to meet our customer’s needs in various applications and demanding production environments.”
