Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

For example, a copper ore grade 1% means that in 100 tons of the ore, we have 1 ton of copper. If the copper ore contains 40 tons of calcite gangue, we can also say 40% grade of calcite in the ore. Suppose we concentrate this ore at 30% grade of copper. Now in 100 kilograms of the concentrate, we have 30 kilograms of copper.

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.
