Slide 16: Why Worry about Water?
Why Worry about Water? ▪ By far, the largest consumer of water is beneficiation, and in particular, flotation ▪ In a typical copper concentrator utilizing flotation: ✓ Total water requirement is 1.5 to 3.5 m3 water per ton of ore ✓ Make up water requirement is 0.6 to 1.0 m3 water per ton of ore 12.4
Slide 17: Why Worry about Water?
Why Worry about Water? ▪ Cost of supplying water is measured in dollars and sense ✓ The 2,500 L/s Escondida Water System desalination plant cost $3.4B ✓ Cost to supply water to the mine is approximately $5/m 3, including: RO Plant: 3.4 kWh/m3 Pumping: 14.0 kWh/m3 (3100m asl, 175km) TOTAL: 17.3 kWh/m
