== 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.
