1. Application
A conventional electrowinning unit consists of a tank, rectifier and pump. Cathodes and anodes are aligned inside the tank. The pump fills the tank with electrolytic solution. Electrical current is provided by rectifier to cathodes and anodes in such way that difference in electrical potential creates a movement of cations towards the cathode. As time goes by the positively charged ions will plate on the cathodes. It is important to note that as metal builds-up on the cathode the deposition of metal in solution will decrease and the plating will slow down. Once the metal deposition decreases to a rate that is not sufficient for electroplating, the cathodes with pure metal deposited will be harvested. In the case of waste water treatment, the solution (waste water) will be cleaned or significantly purified of non-ferrous metals and can be further treated by chemical precipitation or reused within the industrial process.
Our SCR rectifier transformers of MW class has been widely used as a external DC power supply for electrowinning in many countries and got the customer's high praise and affirmation.
