Electrochemical measurements were employed to study the possibility of the extraction of metal ions from lateritic ore leachates predominantly rich in Fe in order to separate more noble cobalt and nickel metals. Lateritic ore was leached in 1 M H2SO4 solution at 70 °C by standard leaching process. The leachate was afterwards subjected to the pH adjustment that led to the removal of Fe ions by precipitation. Results obtained from cyclic voltammetry and chronamperometry measurements in native leachate and those with adjusted pH showed that optimal pH value for Fe removal was 3.7.
Elektrohemijskim merenjima je ispitivana mogućnost izdvajanja kobalta i nikla iz lužine lateritne rude bogate sa Fe. Rastvorne komponente lateritne rude su standardnim procesom luženja, tretiranjem u 1 M rastvoru H2SO4 na povišenoj temperaturi, prevedene u rastvor. U sledećoj fazi prečišćavanja dobijenom rastvoru je podešavana pH vrednost kako bi se joni Fe preveli u talog. Cikličnom voltametrijom i hronoamperometrijom je pokazano da je optimalna vrednost za uklanjanje jona Fe 3,7.
