Electrowinning Cell – for safe and easy metals recovery

Installations normally operate in the buss bar range of 2.1–5 volts and 60–90 amps per cathode and some high-grade solutions will use higher amperage per cathode. Any fumes generated during electrowinning are removed via the local electrowinning cell exhaust system.

Polypropylene Gold Electrowinning Cell

Electrowinning is the process whereby metals, such as gold, are recovered from concentrated solutions by applying a voltage across electrodes immersed in the concentrated solution. The voltage applied across the electrodes (cathode and anode) results in a cathodic reaction which in turn results in the deposition of the metal from solution onto the cathode.The cathode is the …

Strategies for the optimisation of gold processing plants

Increasing voltage to produce greater current will only electrolyse more water and often dislodge gold and produce excessive cell mud. It may also melt the plastic insulation by producing ‘hot spots’. Voltage should never exceed 5 volts. If voltages higher than this are required to maintain current there is another problem.
