High-efficiency silver recovery by electrowinning reduces operating costs and produces a superior product.
Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode.
High throughput, state-of-the-art electrowinning cells provide a low-cost option for silver producers, in particular, and leads to increased profits.
Electrowinning offers a significantly higher efficiency of silver recovery with low operating costs, compared to zinc precipitation methods. In addition, electrowinning produces a very clean silver product that is straightforward to smelt.
