Bu çalışmada, atmosferik basınçta sülfürik asit çözeltisinde Meta Nikel Şirketi’ den (Gördes - Manisa) elde edilen lateritik cevherinin çözünmesi için optimum koşulları belirlemek amacıyla Taguchi Fraksiyonel Tasarım Yöntemi kullanılmıştır. Sıcaklık, liç süresi, katı-sıvı oranı, sülfürik asit konsantrasyonu ve karıştırma hızı parametreler olarak seçilmiştir. Karıştırma yapılmaksızın en uygun çözünme koşulları, 95 °C' lik bir sıcaklık, 150 dakikalık liç süresi, 20 g cevher/100 mL çözelti olan katı/sıvı oranı, % 65 (w/v) sülfürik asit konsantrasyonu olarak bulundu. Optimum özütleme koşulları altında yapılan deneysel sonuçlar, lateritik cevherden nikel ekstraksiyonunun yaklaşık % 90 olduğunu göstermiştir. Deney sonuçlarına varyans analizi (ANOVA) uygulanmıştır. Her faktörün nikelin çözünmesine katkıları yüzde olarak belirlenmiştir.
