One of the world’s largest copper and silver producers has signed a contract worth nearly $US 700 million for the sale of copper cathodes.
Polish company KGHM said Monday it will sell $692,092,994 worth of copper cathodes to MKM Mansfelder Kupfer und Messing GmbH of Germany in 2011.
MKM, which stands for Mansfield Copper and Brass, is a leading European manufacturer of preliminary and semi-finished copper products and copper alloys. KGHM is the world’s seventh-largest producer of copper and the second-largest silver producer.
