ABSTRACT:
In one exemplar embodiment, the present invention comprises a method of making cupric hydroxide that comprises the steps of preparing a suspension of insoluble copper oxychloride in aqueous medium, mixing sodium lignosulfonate into the copper oxychloride suspension for more uniformly dispersing the copper oxychloride particles in the aqueous medium agitating the copper oxychloride suspension and added sodium lignosulfonate until a desired viscosity is obtained, adding sodium hydroxide to the copper oxychloride suspension for reacting with the copper oxychloride to form cupric hydroxide, and recovering the cupric hydroxide.
