John,
See Burt and Wilkie, Manganese Mining in the South-West of England, Journal
of Trevithick Society, 11 (1984), 18-40.
The Roman occupation period iron smelting sites discovered around Exmoor in
the last few years are close to, and possibly exploited, managanese rich
iron ores subsequently extensively worked in the early Bessemer period.
