Using Linear Programming to Minimize Freshwater Use in the Gold
Gold mines deliver gold ore and waste rock to processing facilities, after which the ore is separated from the rock through an 11-stage process. The stages of ore processing require large quantities of fresh-water which are drawn from nearby lakes or rivers. Given the greater importance placed on environmental sustainability, gold …

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. Past ...
