The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Jan 01, 2018· A graph of mass of the ore used in the extraction against mass of the precipitate produced. The results show that the amines and uric acids in chicken waste can complex copper ions from ores just like the acid leached solution. Therefore the copper ions obtained from 6.0 g of the ore were later reduced by hydrazones species prepared in situ.

Copper Mining and Processing: Processing Copper Ores ...

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.
