Lab tests such as this are an ideal way to demonstrate the recovery capabilities of emew for a variety of electrolytes and feed materials. In most cases, these tests can be done right at your site so you can see the results for yourself.
This particular test is to demonstrate the recovery of copper cathode from a copper sulphate feed solution. We can test a range of feed materials to recover not only copper, but also silver, nickel, tin and others. This copper sulphate solution was prepared ahead of time and roughly 3L transferred to the feed tank.
While silver is definitely a precious metal, the usages of this metal are much wider than just the jewelry industry. Silver is a great electro-conductor which makes it a beneficial metal in the manufacturing of electrical and electronic components. Silver is a cost-effective and well performing metal for the industry. For example, it can be used in copper or brass connectors in order to increase conductivity. In other cases, silver is used as an anti-tarnishing plating and can prevent scratches and retain the attractiveness of parts.
Electrowinning is a widely used technology in modern metal recovery, mining, refining and
