It is produced by refining raw copper ore through a process called electrolysis. Copper cathodes are used as a raw material feed for the production of high purity copper and copper alloy products. A cathode is a 50 to 80 kg copper square that is produced when pure copper separates from unwrought copper in an electrolytic refining process.<\/p>\n<p>&nbsp;<\/p>\n<h4><strong>Shipping and Logistic<\/strong><\/h4>\n<p>Bundles of cathode sheets of between 1 and 4 Tonnes and held together by steel strapping are shipped unpackaged. Care should be exercised during handling to avoid straps breaking which cause the bundles to become unstable with potential separation and loss of some sheets.<br \/>\nElectrolytic copper cathodes are usually bought upon a weight basis, and are normally shipped unpacked, often bound together with metal bands. During handling of bundled cathodes, care should be taken that rough handling does not cause breakage of metal bands.<br \/>\nIt is quite common for cathodes to have surface excrescences arising out of the process of manufacture, in the nature of small \u2018pimples or warts. Handling in the course of transit may result in these surface irregularities being broken down and the cathodes delivered with a smooth surface. This may result in a difference between shipped and delivered weights. Cathodes are manufactured with \u2018ears\u2019 for hanging purposes and frequently these \u2018ears\u2019 are knocked off, resulting in further loss of weight.<\/p>\n<p>&nbsp;<\/p>\n<h4><strong>Specification<\/strong><\/h4>\n<p><strong>Copper \u2013 Cu \u2013 99.97% Min.<\/strong><br \/>\n<strong>Silica \u2013 Si \u2013 0.3ppm Max.<\/strong><br \/>\n<strong>Cobalt \u2013 Co \u2013 0.2ppm Max.<\/strong><br \/>\n<strong>Bismuth \u2013 Bi \u2013 0.1ppm Max.<\/strong><br \/>\n<strong>Lead \u2013 Pb \u2013 0.2ppm Max.<\/strong><br \/>\n<strong>Tellurium \u2013 Te \u2013 0.05ppm Max.<\/strong><br \/>\n<strong>Iron \u2013 Fe \u2013 2ppm Max.<\/strong><br \/>\n<strong>Silver \u2013 Ag \u2013 10ppm Max.<\/strong><br \/>\n<strong>Aluminum \u2013 Al \u2013 0.5ppm Max.<\/strong><br \/>\n<strong>Selenium \u2013 Se \u2013 0.3ppm Max.<\/strong><br \/>\n<strong>Manganese \u2013 Mn \u2013 0.1ppm Max.<\/strong><br \/>\n<strong>Sulphur \u2013 S \u2013 4ppm Max.<\/strong><br \/>\n<strong>Nickel \u2013 Ni \u2013 0.2ppm Max.<\/strong><br \/>\n<strong>Magnesium \u2013 Mg \u2013 0.4ppm Max.<\/strong><br \/>\n<strong>Antimony \u2013 Sb \u2013 0.1ppm Max.<\/strong><br \/>\n<strong>Oxygen \u2013 O2 \u2013 0<\/strong><br \/>\n<strong>Arsenic \u2013 AS \u2013 0.1ppm Max.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong>Copper cathode is a pure form of copper that is<\/strong><br \/>\n<strong>used in the manufacturing of various copper products.<\/strong><br \/>\n<strong>It is produced by refining raw copper ore through<\/strong><br \/>\n<strong>a process called electrolysis.<\/strong><\/p>\n","protected":false},"featured_media":16133,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[20],"product_tag":[],"class_list":{"0":"post-16130","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-accessories","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/product\/16130","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/comments?post=16130"}],"version-history":[{"count":1,"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/product\/16130\/revisions"}],"predecessor-version":[{"id":16136,"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/product\/16130\/revisions\/16136"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/media\/16133"}],"wp:attachment":[{"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/media?parent=16130"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/product_brand?post=16130"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=16130"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/metarexllcco.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=16130"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
