HRID 1898749Notes

Reaction equation

[N+:1]([O-:4])([OH:3])=[O:2].[Ni:5](Cl)Cl>>[N+:1]([O-:4])([O-:3])=[O:2].[Ni+2:5].[N+:1]([O-:4])([O-:3])=[O:2]

Participants

Reactant 2

HCID 944Nitric Acid

HCID 24385Nickel Dichloride

Product 1

HCID 25736Nickel nitrate

Procedure

Where hydrochloric or nitric acid is used as the leachant, nickel chloride or nickel nitrate is formed and concentrated following ion exchange. The nickel chloride or nickel nitrate solution is subjected to pyro-hydrolysis to form nickel oxide and recycle acid, e.g. HCl or HNO3.
