Dec 01, 20211. Introduction. Over the past 30 years laterite ores have become increasingly more important as a source of nickel metal (Dalvi et al., 2021).Several methods of nickel extraction from laterite ores have been piloted and some were put into full operation, including acid leach with sulphuric, nitric and hydrochloric acids, ammonia leach and the pyrometallurgical process (Superiadi, 2021).
