WATER STAKES IN THE MINING INDUSTRY

14. 14 Water for the Mining Industry
WATER RELATED CHALLENGES FOR THE
MINING INDUSTRY
Increasingly restrictive legislation & intensified corporate
enforcement on water
 Water footprint is gaining in priority
 Acid rock drainage clean up national legislations (Peru: 300-400 ppm sulfates,
Chile: 1000 ppm sulfates), Australia: [So4] down to 1000 ppm and TDS below 2400
ppm)
 Higher standards seeked for wastewater
Supply constraints
 Water scarcity in new mining operation areas
 Variations in water availabilities due to drought periods followed by flooding periods
Rising tariffs for water supply
Growing reliance on low grade ores requiring more water for
extraction
