Copper cathode

Copper cathodes marks 00 and 0 are manufactured by a method electrolytic refinering , they meet requirements DSTU GOST 859:2003 (GOST 859:2001) and DSTU GOST 546:2004 (GOST 546:2001).


The chemical composition of the cathodes is shown in the table:

Basis for manufacture of cathodes are the copper anode produced at the Enterprise.

The most part of products as semi finished items are further used for manufacture of copper rod.

As finished goods the product are formed in packages according to GOST 21399-75. Packages contain 30-33 cathodes. Height of the package not more than 500 mm, weight up to 2500.
