The originality of this paper is to simulate a block flow diagram of copper SX-EW having a conventional configuration 2Ex2S by using Data from existing copper solvent extraction plants to ...
Then electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. The impure copper is made anode and strip of pure copper are made cathode. On passing the current as shown in the diagram, the pure copper from the anode dissolves into an electrolyte. An equivalent amount of copper is deposited on the ...
Bessemer converter used in extraction of copper: Copper metal is extracted from molten matte through bessemerisation. The matte is introduced into bessemer converter which uphold by tuyeres. The air is blown through the molten matte. Blast of air converts C u 2 S partly into C u 2 O which reacts with remaining C u 2 S to give molten copper.
Jan 02, 2014· EXTRACTION OF COPPER FROM SULPHIDE ORES • Copper is extracted usually from the sulphide ore chalcopyrite (CuFeS2) by smelting process. • Ores containing 4% or more copper are treated by smelting process. • There are following steps for the Pyrometallurgical extraction of copper from Chalcopyrite. 1. CONCENTRATION 2. ROASTING 3. SMELTING 4.
Extraction of copper, zinc, nickel and cobalt in acid oxidative leaching of chalcopyrite at the presence of deep-sea manganese nodules as oxidant. Hydrometallurgy, 2005.
An improved method and apparatus is provided for the production of copper using a solvent extraction electrowinning process. Process streams formed during the process containing entrained liquids are fed to a cyclone to remove either organic extractant or water (aqueous solutions) from the stream. A raffinate stream fed to a cyclone removes entrained organic phase which organic phase may be ...
A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of ...
