Mining: Optimizing gold liberation for milling operations in Nunavut

Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. At Agnico-Eagle’s Meadowbank Mine in Nunavut, an on-line Particle Size Monitor has been employed successfully to achieve the targeted final grind which leads to optimizing the gold recovery at maximum grinding circuit throughput.

The live monitoring of the final product particle size leads to a maximum grinding circuit throughput every minute during the process.

This paper discusses the optimal utilization of the Particle Size Monitor to assist the mill operator to maximize the grinding circuit throughput as the milling conditions change due to variable ore processed at Meadowbank Mine. Also the paper includes the usage of the Particle Size Monitor to guarantee the final grind target at each instant of the process.
