Study of selective reduction in lateritic nickel ore: Saprolite versus ...

2021.1.1 From Fig. 2, the recovery of nickel of saprolite is lower than limonite, which means the nickel in silicate is more difficult to reduce than oxide.From XRD analysis, the forsterite is still found at 1250 °C, and the intensity is seemed similar at a lower temperature. Jiang et al. (2020) reported that a high-temperature process for saprolite was suggested,
