Most of the copper ores mined today are oxide or Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores 11–14, but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching. The process used to treat sulfide copper ores begins at …read more
Copper, zinc and nickel are recovered from the pregnant leach solution by sequential hydrogen sulfide precipitation of separate metal sulfide precipitates. The heaps are typically leached for 1.5 years. The planned production of nickel in the sulfide precipitate is …read more
Three different stages are involved when from non- . 1. Over a very long time and on a vast scale, the reaction of the with a dilute acid such as dilute sulphuric acid produces an extremely dilute sulphate by solvent . 2. a. By solvent , the sulphate is concentrated.read more
Melaconite CuO etc. EXTRACTION OF COPPER FROM SULPHIDE ORE. Large amount of copper are obtained from copper pyrite CuFeS2 by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process.read more
· Best answer. extraction copper from its Sulphide Ore, when ore is subjected to roasting some is oxidisedto Cu2O which reacts with remaining Cu2S to give copper metal. In this process, Cu2S behaves as reducing agent. 2Cu2S+3O2+heat→2Cu2Os+2SO2gread more
· There is a growing interest in exploring the application of bioleaching for treating of decreasing grade and located at larger depth by in situ recovery ISR for potential savings in , crushing, grinding and the avoidance of tailings.read more
The commonest ore used in the extraction of copper is Chalcopyrite CuFeS 2 also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.read more

is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting. The obtained oxide is then reduced with carbon or any other suitable reducing agent to obtain the metal.read more
