Results are reported for the computer simulation of heap leaching of mixed copper oxide and sulphide ores.they resemble those obtained from testwork in terms of a substantial peak in the copper concentration of the pregnant solution, an initial period when no copper emerges and a lengthy period towards the end when the copper concentration.
Sep 01, 1998nbsp018332this paper discusses the modelling and simulation of the hydrometallurgical processes.the simulation example of a copper heap leaching process is presented and evaluated..generic classes are created for the operational units.for streams.which connect these units.and for text labels..copper95 -cobre95, vo1.3, chile, pp.773 780.

Heap leaching is a metal extraction process from low grade ores where crushed ore is stacked on an impermeable pad and irrigated from the top with a solution of chemical reagents.an enriched solution containing the targeted metal is collected at the bottom.this technique involves complex chemicalelectrochemical reactions and transport processes.among the main features of this method.
Leaching in place requires prior fracturing of the ore body by explosives to provide cracks for percolation of leach solution.copper-containing percolate is recovered for recirculation and eventual metal recovery by pumping this solution from lower.percolation leaching of copper ore - breservenpercolation leaching of bornite ore - ausimm.
