Mine Water Management

Mine Water Management Overview
Tony Rex, Tom Sharp

As the mining industry focuses on improving productivity, reducing operating costs, and venturing into ever more challenging and remote locations for new projects, there is an increased need to look upon water as a whole-project issue.
