Mount Milligan mine performance update, 51st Canadian Mineral Processors conference, 22-24 January 2019, Ottawa, Canada

ABSTRACT

The Mount Milligan mine, located in central British Columbia, began operation in September 2013 with a design nameplate capacity of 62,500 dry metric tonnes per day, using a conventional SABC grinding circuit followed by bulk sulphide flotation. Over the last few years, many changes have been implemented in order to debottleneck and optimise the comminution circuit to meet and exceed the nameplate design capacity as well as improve the metal recovery of the flotation circuit.

This paper discusses changes, grouped into mechanical modifications, projects, and operational changes. The implementation of these changes as well as ongoing challenges and potential solutions will also be discussed.
