Its consumption in gold processing is high; and (3) The gold recovery step requires more development. Reagent consumption is exceedingly high because thiourea is readily oxidised in solution, and as Presad et al. [18] implies, the high costs attached to leaching are likely due to the thiourea process still being in an infancy stage. Pasthigh value, products such as gold where water is needed to transport and process very low grade ore. Over 250 ML of water is required to produce a tonne of gold, but the price of gold is so high that it still represents a value added of $80 000 per ML of water used.10 At the other extreme, petroleum companies useWater in mining and industry CSIRO PUBLISHING
