Abstract

An investigation has been carried out to study the feasibility of the removal of nickel from ammoniacal solutions using the reducing agent sodium dithionite. The results obtained indicate that dithionite can precipitate over 95% of nickel values in solution in the form of Ni3S2 and metallic nickel. A temperature of 45°C has been found to be optimal for the precipitation process.
