FAQ: emew VS Conventional Electrowinning
Q1: Why does the emew cell outperform conventional electrowinning technology? A1: The high performance of the emew electrowinning technology is achieved through a hydrodynamic mechanism, which achieves higher rates of metal ion transport to the cathode than in a conventional electrowinning reactor. The essential difference is that the emew cell is …

ELECTROWINNING CELLS
The cathodes are removed from the cell using an overhead hoist and cathode lifting rack. The cathodes get transported to a cathode wash bay where the cathodes are washed using a high pressure washer. Post the removal of the cathodes, sludge that accumulates in the cell is washed via the sloping channel at the bottom of the cell and collected.

Electrowinning
Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode.. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4. The overall reaction is the combination of two electrochemical half reactions.
