Point Mills Arsenic Refinery

Point Mills Arsenic Refinery

All that remains of the Point Mills arsenic refinery near Bissoe is this chimney. The British Arsenic Company (which became the Cornwall Arsenic Company) operated these works for a century, ending with the outbreak of WW2 in 1939.

Arsenic is a byproduct of the tin smelting process but also had an important commercial use. The arsenic produced by these works was of a particularly high quality and was exported for use in cotton plantations where it was used in insecticides to control boll weevil

The arsenic works now lie on the Bissoe / Devoran trail adjacent to Bissoe Valley Nature Reserve.
