26 MINING & TECHNOLOGY AUSTRALIA 2014 | ISSUE 8 Continuous Ionic Filtration™ promises improved fltering of metals and salts from mine processing & high rates of clean water recovery. Australia's leading science agency the CSIRO has been just as active. One of its most recent breakthroughs is "Virtual Curtain" which purifes water more sustainably by utilising hydrotalcites to simultaneously trap a variety of contaminants, including arsenic, cadmium, and iron, without the need for complex infrastructure or chemistry. Commercialisation of the technology is underway with Australian company Virtual Curtain and is receiving notice internationally. End use is also changing as the water quality from mine dewatering or waste improves. Rio Tinto began using water from its iron ore sites in the Pilbara to grow crops back in 2011, AGL is doing the same using blended water from coal seam gas wells outside of Gloucester in New South Wales, at the same time QGC has gone one step further under its 'Benefcial Use Scheme' to supply drinking water to Chinchilla residents after treatment, part of the $1 billion it expects to spend just this year on water-related treatment facilities and related activities. Despite a growing fxation on treatment and new technologies, many right across the mining, engineering and water sectors warn that systems do not necessarily need to be complex or expensive, but should be designed properly from the start. "Balance of water supply and use, system simplicity and practicality, cost effectiveness and sustainability are keys to best practice water management," Sam Pollard from Hyder Consulting said. "It is a process always of also balancing the mines capital and operating expenses and TECHNOLOGY & INNOVATION with water that means looking the whole site design in a long term way." Resources on tap WATER'S GROWING PROFILE FOR miners is only set to continue, both as a business practice and a sustainability trigger. Despite a comparatively low and stable water consumption of around four percent – roughly 500 gigalitres – of Australia's total use, it can vary widely across the country and between regions. It's also expected to start rising as coal production
