| description | Apparatus and process for continuous electrowinning of copper bearing slurries, including an electrowinning cell wherein a slurry composed of a suitable electrolyte and a copper-bearing solid material, is subjected to the simultaneous reactions or dissolving the copper material and plating out elemental copper as a relatively pure copper product. The apparatus and process also includes means to purify the copper-bearing material before passage to the electrowinning cell so as to prevent contamination of the electrolyte in the cell and, also, a means to recover sulfur which is released during the electrowinning and unreacted copper material. The slurry is produced by acid-leaching of copper-bearing solids and adding calcium sulfite to the acid solution to form copper precipitate solids. |
