Latest Patents
Kojur N Subramanian holds a patent for a method titled "Nickel recovery from sulfur-deficient mattes." This patent describes a process where a nickel matte, characterized by an atomic ratio of S:(Ni+Co+Cu) of less than 0.7, is fragmented and slurried with water or an aqueous nickel sulfate solution. The slurry is then heated under pressure in the presence of oxygen to form a basic nickel sulfate. Following this, the reacted slurry is treated with lime to convert the basic nickel sulfate into nickel hydroxide. The nickel hydroxide is subsequently separated from gypsum through physical separation and dissolved in spent sulfate electrolyte to generate fresh electrolyte from which nickel can be electrowon. This innovative method enhances the efficiency of nickel recovery and contributes to more sustainable practices in the industry.
