Since most mining operations in arid regions are zero-discharge facilities that don’t produce grey water, chances are slim today’s mining operators can share water with municipalities in times of drought.
In February, the Society for Mining, Metallurgy and Exploration (SME) held its second international symposium on water in mineral processing.
Those mining professionals and consultants in attendance viewed the event as pivotal in focusing miners’ attention on what they believed would emerged as mining’s hottest issue—water management strategies and their critical role in securing mining’s social license in the permitting and operation of mining projects and expansions.
Much was made by those presenting papers to SME that “opportunities abound for mine water reuse,” which can help with community water needs. In the future, mine wastewater could be reused for irrigation, steel manufacturing, hydraulic fracturing, or cooling and power generation, consultants advised.
