摘要：The application and development of goethite process were hindered by the poor filterability of the precipitate and the great loss of nickel in nickel hydrometallurgy. In this study, the effects of pH on the goethite precipitation and the mechanism of the nickel loss were investigated. The goethite precipitation at a lower pH (2.4 to 3.0) guaranteed a higher recovery of nickel at the cost of the filterability of the precipitate. Then a novel process, magnetic seeding and separation, was proposed to improve the filterability of iron residues and simplify the iron removal process. The iron precip
