Rönnskär

Rönnskär () is a metallurgic plant located in Skelleftehamn, Sweden. The factory does extraction of copper, zinc and lead, and produces important quantities of sulfuric acid, silver and gold when extracted as joint products. Since 2012, electronic waste recycling has become a major activity of the factory. Launched in 1930 as Rönnskärsverken, Rönnskär is Boliden AB's main production site.

== History == Gold discovered around Boliden in 1925 and important mineral deposits in Skellefteå accelerated the region's industrial growth. Minerals in Boliden contained high levels of arsenic, so in 1927 it became a priority for the country to develop its own extraction capacities of its own minerals.
