Copper Ore Types: Sulfides versus Oxides. These oxide ores are usually leached by sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate in solution. The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning (SXEW) plant.

Keywords: hydrometallurgy, hydroxyoximes, LIX, copper ore, copper concentrate Introduction Ammonia leaching is frequently used in hydrometallurgy for processing of oxide and sulfide ores, concentrates or byproducts, particularly those containing significant amounts of carbonate rocks, which during the acidic leaching contribute to increased
Selective leaching can also be achieved with a nonspecific solvent if the ore dissolution reactions are much faster than the gangue dissolution reactions. An example of this is a copper oxide ore deposit where copper oxide minerals are much more soluble in dilute sulfuric acid than matrix gangue minerals such as quartz or feldspar.

recovery of copper from oxide copper ore by flotation and METU. Dec 2, 2014 The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H2SO4) leaching.
Mixed copper ores are treated through different processes depending on the degree of oxidation as well as the consumption of acid. With the availability of realtime technology that can reliably measure differences between oxide and sulphide minerals, it is now possible to control a mixed copper ore .
The flowsheet discussed in this study is for treatment of 100 tons per day oxidesulfide copper ore by the leaching process using sulfuric acidferric sulfate solvent. This flowsheet would also be suitable for a larger tonnage by proper sizing of the various units of equipment.
All Answers ( 8) Ammonia leaching of the converted oxide copper can also be contemplated. There are pros and cons for each option. Note that typically for a high purity copper product, further leach solution purification may be required prior to final copper production, this is usually done with solvent extraction and electrowinning.
