Abstract
In the atmospheric acid leaching process of low-grade nickelferous laterite, the leaching mechanisms still remain unclear when sulfuric acid is used as the leaching agent. It is therefore imperative to study the leaching characteristics of Ni-doped goethite. In this work samples of goethite and nickeliferous goethite were synthesized and characterized by chemical composition, surface area and XRD analyses. The results show that part of nickel is incorporated into the lattice of nickeliferous goethite. The synthesized nickeliferous goethite was pre-leached in diluted hydrochloric acid at 25°C to separate the adsorbed nickel. Subsequently, the Ni-doped goethite in which nickel is completely distributed within the lattice was leached in sulfuric acid. The results indicated that the extraction of Ni was incongruent with that of Fe. Sulfuric acid leaching kinetics of Ni and Fe are characteristic of chemical reaction and internal diffusion controlled processes, respectively.
