TIDBITS OF INFO-SWEDENMay 1, 1920 MINING AND SCIENTIFIC PRESS
SWEDEN
Copper mining in Sweden has not been nearly so important of late years, as in times past. The average yearly production for the period 1891-1895 was 23,941 tons, whereas in 1916, the output was but 1380 tons. In 1917 however, there was an increase to 13,193 tons. The principal mines are at Falun and Helsingborg. The latter, it appears, works the burnt pyrite obtained in the manufacture of sulphuric acid, into copper.
