Balen/Overpelt Smelter Belgium

OVERVIEW Fast Facts The Balen smelter is one of the world’s largest smelters in terms of production volume. LOCATION: Balen and Overpelt, Belgium The Balen and Overpelt sites are only 18 kilometres apart. The TECHNOLOGY: roast, leach, electrolysis (RLE) , oxide washing sites’ operations are complementary and highly integrated. Cathodes produced at Balen and Auby (France) are transported to PRODUCTS: special high grade (SHG) zinc, zinc alloys the centralised melting & casting facilities in Overpelt. In addition, and sulphuric acid the Overpelt site includes one of Europe’s largest oxide washing EMPLOYEES: 552 facilities that serves as a central washing facility for the pre- treatment of purchased secondaries prior to their consumption PRODUCTION 2016: 236,000 tonnes zinc metal, 317.000 by the European Nyrstar smelters. As part of the casting facilities tonnes sulphuric acid upgrade, a new melting furnace and a completely automated casting line were installed and commissioned in Overpelt in June 2010. SHG casting capacity at Overpelt amounted to 235.000 tonnes in 2016. The Balen smelter produces zinc from feedstock of both zinc concentrates and recycled zinc secondary feed materials.

The Balen smelter can process a high percentage of secondary feed material input without adversely affecting overall plant productivity, effi ciency or residue output. Concentrates are transported by train from the port of Antwerp, a main Operation at a glance thoroughfare harbour for zinc concentrates. Secondary zinc feed materials are delivered to the plant by truck. The Balen smelter is located in the north-east of Belgium, and is a large-scale smelter. The Balen and Overpelt operations produce SHG zinc and a range The Overpelt plant is situated only 18 kilometers from Balen, of high value alloy products such as ZAMAK die casting alloy. consisting of one of Europe’s largest oxide washing facilities, as well Balen also produces sulphuric acid, copper cement and Balen Leach Product that contains lead and precious metals and is sold as signifi cant alloying and casting facilities. as a raw material to secondary smelters.
