Boliden's value chain Value chain Exploration Meeting the demand for metals and securing Boliden's long-term growth requires extractable ore reserves, today and tomorrow. Exploration – the search for mineral deposits – is conducted both in the vicinity of existing mines and in new areas. Boliden's exploration focuses on deposits that contain zinc, copper and precious metals. Mining Boliden extracts ores from open-pit mines as well as underground mines. The ores extracted are transported to concentrators in the respective mining area, where they are processed into metal concentrates. The majority of zinc and copper concentrates are further refined into metals at Boliden's smelters. A certain volume of concentrates is sold to external customers. Smelting Boliden's five smelters possess a high degree of process-technological expertise, flexible smelting processes and an ability to produce high-quality metals from complex mined concentrates and secondary raw materials. The smelters produce zinc ingots, copper cathodes, lead ingots and gold and silver granules, along with a number of by-products and small quantities of other metals. Market The majority of Boliden's metals and other products are sold to industrial customers in Europe. Zinc is supplied to steel companies, amongst others, while copper is supplied to manufacturers of wire rod, copper rods and copper alloys. The automotive and construction industries are important end-consumers of base metals. Many of Boliden's byproducts are sold as raw materials to other industries.
