HCID 86585150Sulfuric acid nickel sulfate

Procedure

Sulphuric acid/nickel sulphate strip solution (84) is introduced into mixing stage (83). Following mixing, the organic and aqueous phases are allowed to separate out at stage (85) to give the barren organic extractant (86) in the upper layer and a nickel sulphate rich solution (87). This solution (87) is transferred to a nickel electrowinning stage (88) where nickel metal (89) is produced as well as sulphuric acid/nickel sulphate strip solution (84).
