The separation mechanism of nickel and iron by sulphide precipitation and process influence conditions were investigated. The results showed that the separation and enrichment of nickel and iron were influenced by temperature, the value of pH, mode of addition of sulphidizing agent and complexes, in which the value of pH influenced the most. Nickel and Iron can be well separated by well controlling the value of pH and selecting proper temperature and mode of addition.
