Goethite is a dominant component of nickel laterite ores, which is capable of adsorbing metal ions in water. The potential of the unused low-grade nickel ore (LGO) to treat synthetic acid mine drainage (AMD) was investigated. LGO characterization identified the presence of goethite (α-FeOOH), calciu...
