The Challenge The cost effective use of water in mining operations is vitally important. Customers need to understand how to optimize the use of water in mineral processing in order to enhance mineral recovery and ultimately increase mine profitability. Similarly, community concerns and regulatory uncertainty can have a direct effect on schedule outcomes, commodity sales and return on investment. As a consquence a key challenge we see emerging for our customers is that of developing a responsible water stewardship approach that embraces all aspects of water management including, abstraction, discharge, and treatment and recycling.
Challenges throughout project life-cycle Determine the water business case Mine water management (sourcing and disposal of water)
Community concerns around water supply and quality Social license to operate
Water system selection Water system establishment
Water use efficiency and targets Reporting and measurement Treatment and reuse/disposal of process water Managing water costs Water system maintenance
