Electrowinning (EW) TENOVA

In this manner, we are able to optimize the weight of copper required and thus decrease its cost. The Tenobar™ is in addition to an equalizing bar and allows for a double contact on the anode, which therefore: Decreases stray currents; Increases the life of the anode life; Increases copper quality; Decreases electrical energy consumption

Electrowinning an overview ScienceDirect Topics

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.

Electrowinning Science method ResearchGate

In copper solvent extraction, aqueous-in-organic entrainment results in the carry-over of unwanted species into the electrowinning process with negative cost implications.
