Slide 17: Mean results from the industrial UF/RO plant (May 2018)
Mean results from the industrial UF/RO plant (May 2018) Average clean water output: 400m3/day * The CN is free cyanide in all cases except for Final output which is the sum of Free + WAD cyanide 17
Slide 18: UF/RO Water Treatment Plant Cost Data
UF/RO Water Treatment Plant Cost Data Data for May 2018 Power consumption (month) = 67000 kwh Power cost (month) = 5140 AZN (USD 1 = 1.7 AZN) Clean water production (month) = 12500 m3 (403 m3/day) Power consumption = 5 kwh/m3 Unit cost = 0.41 AZN/m3 = 24 cents US/m3 c.f. Transported water from river
Slide 19: Conclusions
Conclusions • Laboratory and pilot plant tests showed that a combination of ultrafiltration and reverse osmosis can be used to produce clean water from cyanide leach solutions that are saturated with calcium and contain up to at least one gram per litre of copper. • An industrial-scale UF/RO plant h
