Mines and environmental impact

Mining waste has different characteristics depending on the type of ore being mined. Our Swedish ores can be roughly divided into oxidic and sulphidic ores. The oxidic ores predominate in Norrbotten's iron ore field, while the sulphidic ores are more prominent in, e.g. the Skellefteå field in Västerbotten. However, Sweden's.
