Since the late 19th century it has been known that alum shale from the table mountains of Västergötland contained uranium.

As part of the Swedish nuclear fuel programme, uranium was extracted from alum shale near Ranstad, between Skövde and Falköping, between 1965 and 1969.

The mine was known as Ranstadsverket and yielded around three grams of uranium per ton of alum shale. However, by the late 1960s this yield was too low to make the mine profitable, and it was shut down. Over the four years that the mine remained in operation, around 250 tons of uranium were extracted from 1,500,000 tons of rock. A number of attempts were made to resume mining in the 1970s, but following protests from local people this never became a reality.
