Tankhouse Expansion And Modernisation Of Copper Refineries Ltd., Townsville, Australia

Copper Refineries Ltd. (CRL), Townsville is Australia's largest producer and exporter of refined copper cathode. This status has been maintained by the implementation of a significant capital works program that increased the production capacity to 270,000 t/y by June 1999. In 1979, CRL was the first in the world to commission the ISA Process Technology which has now been marketed to 47 licensees worldwide. The new tankhouse design has focused particular attention on customer requirements, operational improvements, materials handling and equipment modernisation. Equipment which has been upgraded includes cranes, anode preparation, cathode stripping and scrap washing machines along with the total replacement of the electrolyte and electrical reticulation systems. Side stream electrolyte filtration has been introduced. Improvements to electrode alignment afforded by the conversion to polymer concrete cells, precise electrode location, and the upgrade of the electrode handling machines will ensure that CRL. continues to be one of the world's major quality copper cathode producers.
