Dressing the Ore Cornish Mining WHS
Copper dressing relied extensively on manual labour throughout the 18th and 19th centuries, though mechanisation did play a part. Copper crushers (''Cornish rolls'') were introduced in the early 19th century and low grade or otherwise difficult ores were also stamped at some mines. Copper ore was spalled in the same way as with tin.
