Smelters - Boliden

Boliden develops its own methods for waste disposal. The smelting plant at Odda disposes waste in an underground cavity and Rönnskär is building a unique storage around 350 metres underground that will begin use in the 2019/20 new year. Underground storage is a long-term, sustainable solution for final disposal of smelter waste.

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
