Refined copper cathodes are produced from anodes or from leaching low-grade sulphides in the SX -EW plants. They are used for wire, cable and conductors as well as for other industrial uses such as manufacturing pipes and profiles.

Sizes and Characteristics:
Electrolytic Cathode
Square-shaped plate of approx. 1.0/1.1 m x 1.0 m weighing, 132-185 kg. approx. per piece, with 3.0 – 3.5 cm. thickness.

Electro won Cathode
Square-shaped plate of approx. 1.0 m by side and weight that varies between 25 y 60 kg., approx. 8 mm. thick. Both cathodes qualities can be either corrugated or flat in metal-banded packages of approx. 19 pieces each.

Assays:
Cu : 99.99%


 

Wire-shaped refined copper is obtained from cathodic copper at La Caridad Plant or at the Amarillo-Texas Plant of Asarco under a toll process. It is used for cable manufacturing.

Sizes and Characteristics:
Rolls of 143 cm. of external diameter and 100 cm. of internal diameter, average height of 85 cm. Average weight of 3250 kg.

Product Properties:
Electric Resistivity 0.15176 ohm. Electric Conductivity 101%, Tension 22.24 Kg/mm2, Average Elongation 40%, Average tension to rupture 50 turns.
