Jan 14, 2019· Under electrical charge, copper ions migrate from the solution to copper starter cathodes that are made from high purity copper foil. Other elements that may be present in the solution, such as gold, silver, platinum, selenium, and tellurium, collect in the bottom of the tank as 'slimes' and can be recovered through further processing.

The following process is usually used to obtain cadmium produced from flue dust collected at lead or copper smelters. Concentrates of copper, and especially lead, contain considerable amounts of cadmium. In copper smelters, the cadmium reports in flue dusts, which are collected and recycled through the smelter system to upgrade the cadmium content.
