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...

Copper processing - Ores Britannica

The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step, involving either smelting or leaching, removes a large proportion of impurity elements—in particular iron and, in the case of sulfide ores, sulfur.

The Dressing floor operation at South Caradon Mine

The layout of a copper mines dressing floors was greatly influenced by the properties of its main ore Charcopyrite. This ore tended to be hard and brittle with the unwanted property of easily breaking into a very fine powder. Tin mines traditionally operated by stamping all the ore and then classifying and concentrating the crushed rock through a series of physical processes using water. Such an approach applied to Copper ore would lead to large amounts of the ore being carried through the ...

Minimizing downtime due to mineralogical ore variability. Based on recent data Chadwick, 2011 , the major copper producers need to replace an average of almost 480,000 t of Cu production in reserves each year. The new reserves require substantially more mineralogical characterization in order to avoid poor processing performance.

Mineral processing - Wikipedia

A later example was the Cornish stamps, consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ore under gravity. The simplest method of separating ore from gangue consists of picking out the individual crystals of each. This is a very tedious process, particularly ...
