        leaching conditions must aim on shorter leaching times as well as on a higher copper extraction rate, thus to an increase in copper productivity and lower costs per ton of copper. Because leaching processes include interactions between solid (ore) and liquid (sulfuric acid) phases such improvements may be achieved by the use of wetting agents.
