The New Electric Furnace Of Norddeutsche Affinerie

Norddeutsche Affinerie is the largest West European copper producer with an annual output of more than 350,000 tonnes of refined copper, about half of which is produced from copper concentrates. However, in addition to concentrates, Norddeutsche Affinerie processes secondary raw materials and recycling materials which contain a combination of copper and lead. These materials were previously treated in blast furnaces, a technology which has meanwhile been superseded at NA by the electric furnace process, primarily owing to the necessity of complying with the increasingly stringent requirements for environmental protection.
