Elkem Silicon Products Salten

The plant is located in Straumen, 1150 km from Oslo and 1000 km from North Cape.

Construction of the plant began in the mid-1960's and the first electric smelting furnace came into operation in 1967. Three years later a second furnace was added, and in 1972 the third and largest furnace began producing ferrosilicon.

Over the years, the operation has been upgraded ferrosilicon production towards higher silicon purity and Elkem Salten is now one of the world’s largest and most modern silicon plants exporting silicon and silica fume products worldwide.
