Introduction. Ferronickel (FeNi), with CAS number 11110–39-7, originates from nickel sulfide and oxide ores and contains around 55–75 % wt Fe and 25–45 % wt Ni [1].The depletion of nickel sulfide ores and their challenging extraction have prompted the exploitation of nickel oxide ores [2].Limonitic and saprolitic are typical nickel oxide ores …
