something to ponder

Past uranium production from the Alum Shale

The Alum Shale has been mined as a source of uranium in the post-war period in both Sweden and Estonia, a Baltic state southeast of Sweden.

An operation to extract uranium from the Alum Shale began at Kvarntorp in southern Sweden in 1965. 400,000-500,000 tonnes of ore were mined per annum; the plant had a nominal capacity of 120 tonnes of uranium per year.

The plant operated for 5 years before closure because of low uranium prices. Recoveries of uranium in the plant were 80% at closure

this site shows the price of uranium around 1965 at hte time of the mine at around $10-$20 lb now at recovery of 98% and price of $50 lb this has to be viable now,
