Precious Metals Recovery Technological Data
Precious metals recovered and refined from scraps in the electronic, electric, petrochemical industries are recycled.
Recovery and refinement methods for precious metals
It is classified as below by its recovery pathway and feature that the Recycling method
of Precious Metal, and we get highly purified precious metal by selecting the best
proper method for the condition of the objects.
Electrorefining
Electrochemical purification method is divided into two methods of ElectroPurification and Electrowinning method, and ElectroPurification is used in general.
Electrorefining
In electrorefining, a low purity metal plate is made into an Anode(+) and a insoluble electrode or high purity metal is used as a Cathode(-). Over time, the low purity Anode melts and a high purity metal is educted on the Cathode.
Electrowinning
In electrowinning, low purity metal ion is dissolved in a electrolysis solution that is linked with insoluble electrodes Annode(+) and Cathode(-). Over time, the metal ion in the solution decreases and is educted on the Cathode.
