Bavarder sur Internet2024.3.26 The sulfation roasting leaching process has been investigated as an alternative method for recovering nickel and cobalt from laterite ore. This process involves converting the nickel and cobalt in the ore into sulfates, which can then be dissolved through water leaching, while the iron remains as an insoluble oxide. However, the presence of
