Tailings & Engineering Design
We have in depth engineering experience and good concept and theoretical abilities in tailings facilities design. Our design methodology and approach are grounded in principles of defining the key design drivers of liquor or water balance, tonnage and storage requirements and environmental drivers such as geochemistry and seepage fate, dusting and the long term closure plans.
A representative list of projects includes:
- Engineering lead for the new TSF5 storage facility at Olympic Dam from identification stages to commissioning and operations handover
- Principal Tailings Engineer for the Olympic Dam expansion studies involving data collection and test programs ie, geotechnical and geochemistry studies, design, engineering and estimates
- Principal Tailings engineer as well as Lead on the water and mining studies for development of the Yeelirrie uranium deposit (identification and selection studies)
- Design and construction of a new dam for storage of the wash plant fines at Peak Downs mine
- Operations interface for the design, construction and commissioning of the Laguna Seca tailings facility at the Escondida mine. Due to the ability to communicate in Spanish, was also directly involved with the design team; Klohn Crippen
- Planned the mine paths and the tailings stacking at BHP NZ Steel’s mine sites at Waikato North Head and Taharoa
A representative list of mines and projects in which we have worked include:
- Olympic Dam, SA – Copper, uranium, gold and silver)
- Yeelirrie, WA – uranium
- Peak Downs, QLD – metallurgical coal
- Escondida, Chile – copper, gold
- BHP New Zealand steel – iron ore
Others include Mt Isa (lead, zinc), Kloof Gold mine, RSA – gold; and Huntly and Strongman collieries in NZ – coal.
