Mining is one of the industries with the highest energy and water consumption. In Australia, the sector can account for around 10 per cent of the nation’s total energy use. Reducing the level and impact of this energy use is imperative to improving sustainability metrics and reducing costs. Most underground and open cut mines feature complex hydraulic networks with water used for processes such as drilling, air conditioning, dust abatement, leaching, flotation, tailings transportation. In many sections of a mine’s hydraulic network there are opportunities to recover excess hydraulic energy and convert it to electricity. The renewable power generated can either be fed directly into the mine’s internal power grid for self-consumption or can be used locally for applications such as the charging of Battery Electric Vehicles (BEVs). This article presents three recent case studies undertaken by the authors, describing and comparing the design, installation and operation of Pumps As Turbines (PAT) as hydropower energy recovery devices in different areas of mining infrastructure. The cases illustrate the technology and the collaboration with the mine operators. As a set, these installations can generate around 1 GWh annually, preventing 210 t of CO2 emissions per annum and generating economic savings through reduced energy purchase. Finally, the potential for industry-wide adoption of this technology is outlined.
