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

Mine-site Water Management Service Response Surface water and groundwater monitoring and modeling

Water and wastewater treatment and system delivery

WorleyParsons’ technical specialists are supported by a multidisciplinary team to provide customers with an integrated offering to effectively manage risks and monitor all mine affected watersheds, aquatic bodies and surface water runoffs, as well as to support the application for water licenses and regulatory approvals for waste discharge.

WorleyParsons works at every phase of development, delivery and operations for source water, wastewater and industrial process water treatment systems. We specialize in water and wastewater characterization, assessment, treatment and recycling. Our approach is to collaborate with our customers to produce tailored treatment and management strategies, as well as mitigation and remediation programs.

Our mine hydrogeologists specialize in dewatering and depressurization to prevent groundwater intrusion into mining operations. WorleyParsons’ groundwater services range from initial technical desktop assessments, preliminary site investigations and hydrogeological conceptualization to the design and project management of groundwater drilling, exploration and monitoring programs.

Tailings and waste management WorleyParsons provides customers with a range of cost effective, environmentally sustainable and stable tailings delivery and storage solutions. We have extensive experience in the planning, engineering design and environmental management of tailings facilities, dams, ponds and mine waste dumps.
