    <subfield code="a">Nontronitic and limonitic type laterites from "Gordes" nickel deposit located in Western Turkey were subjected to sulfuric acid leaching at atmospheric pressure. Experiments were conducted in order to determine the optimum conditions for agitation leaching by studying various parameters, including time, acid concentration, leaching temperature and particle size. Agitation leach experiments showed that nickel and cobalt could be extracted from both ores. Nickel and cobalt extractions were 96.0% and 63.4% for nontronite: 93.1% and 75.0% for limonite after 24 h of leaching at 95 degrees C, respectively. Overall acid consumptions of ores under the optimum conditions were 669 kg H2SO4/ton dry ore for nontronite and 714 kg H2SO4/ton dry ore for limonite.</subfield>
