Cathode - Global Copper Ltd.
A cathode – a 50 to 80 kg copper square – is produced when pure copper separates from unwrought copper in an electrolytic refining process. Global Copper Ltd. produces about 1.2 million t of cathodes with a copper content of at least 99.99 % per year). This product is important for the production of ray, cathoderay tubes and are used for cathodic protection.
This element is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathodes Current Departs. A conventional current describes the direction in which positive charges move.
