Copper Oxide Flotation - Mineral Processing & …
Continuing with the evaluation of copper oxide flotation using hydroxamate we now evaluate a rock that’s 41% copper oxide with some lead oxide included. Sample B: 1.8% Copper about 41% Oxide Cu. Rougher Tests: Unseen in these charts is the order in which the results were obtained. The last/best “Blue” dot (the best data point) was the last test of the series.

These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate solution.
Copper Mining and Extraction: Oxide Ores
In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW (Solvent Extraction – Electrowinning). The acid would have to be made anyway as it would be environmentally unacceptable to release sulfur dioxide gas into the atmosphere.
Treatment of Mixed Sulfide Oxide Ores of Copper
That the oxide orebodies may be treated as at New Cornelia for extraction of the soluble copper; then reground and sent through regular flotation treatment. That some ores, with a rather high content of soluble copper, may be treated by leaching-precipitation-flotation. That some low-grade ores will be successfully treated by heap leaching.

12. Flotation of Copper Sulfide Ores 12.5.1 Flotation of sulfide copper ores Sulfide copper ores are considered easy to treat provided that the main copper mineral is chalcopyrite. In case the ore contains secondary copper minerals, such as chalcocite, bornite and covellite, depression of pyrite may be a problem because the pyrite can be ...
