Boliden's metals are mainly sold and transported by rail, sea, or road to industrial customers in Europe. The largest part of our zinc customers are large steelworks which use zinc to protect steel from corrosion when manufacturing galvanised thin sheet. The second largest customer category comprises companies that hot dip galvanise piece goods. The majority of our copper customers are manufacturers of wire rod, copper rods and copper alloys who, in turn, sell their products to the construction, electronics and automotive industries.
Boliden buys metal concentrates from its own mines and from approximately 20 suppliers and have around one hundred suppliers of electronic and metal scrap and other secondary raw materials. We also have around 6,800 suppliers of goods, services and logistics. Just over 200 of this total accounts for the majority of purchasing volumes.
