A novel electrowinning process using an emew cell was developed to recover bismuth and copper from a copper electrorefining waste stream. Significant removal and co-deposition of copper and bismuth were achieved from a highly acidic sulfate industrial effluent using a current density of 350 A m 2, but the current efficiency was low (27%).

At present, the hydrometallurgical process generally involves leaching, extraction, and electrowinning of secondary copper resources with a low copper content. Owing to the high impurity of copper leaching solution, it is difficult to electrolyze high-purity copper products by direct electrowinning.
Electrowinning has proved to be an effective and simple method for recovering gold from the eluate. Electrowinning is done simultaneously with the elution. The barren eluate is recycled to the eluant tank and is recycled for the next elution after the reagents have been made up to their relevant concentrations.
recently, a new electrowinning technology, the emew® cell, has been developed based on re-design of the electrowinning chamber. 14, 15 the cell is constructed from a pair of concentric...

Copper Electrowinning. Typical of electrowinning from aqueous solutions is copper electrowinning. The electrolyte entering the cells contains 25–60 g l-1 of copper, 50–180 g l-1 of sulfuric acid, and 5–10 g l-1 of iron salts (Habashi, 1998). It is produced by leaching of copper ores, with solution purification by solvent extraction.
