Mineral processing - Wikipedia

This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina, Tasmania, magnetic separation was used to separate the ores. At these mines a device ...

Dressing the Ore - Cornwall Council

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.
