Abstract

Batches of hydroxide sludges are successively converted with various reagents in a reaction container, thus transforming by oxidation the chrome hydroxide into chromate. The zinc hydroxide is extracted by alkalis. The chrome hydroxide in the residue of the alkali processing is oxidized into chromate. Copper and nickel are extracted with acids from the oxidation residues. The remaining residual sludge contains essentially iron hydroxide. Copper oxide is precipitated from the solution, separated from the nickel solution and finally dissolved in acid. The separation can be carried out in a single container and supplies the separated components of the hydroxide sludge in a form that allows these components to be recuperated as useful materials.
