The Extraction of Copper · Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silie, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of ...

Copper Sulphate(CuSO4) | Reference Notes | Grade 12 ...Copper Sulphate (CuSO4) Copper Sulphate pentahydrate (CuSO 4 5H 2 O) is commonly known as Blue Vitriol. It is obtained in lab by dissolving CuO, Cu (OH) 2 or CuCO 3 in dil H 2 SO 4. The solution on crystallization gives blue triclinic crystals of CuSO 4 5H 2 O. In large scale, CuSO 4 is obtained by reacting scrap copper with hot and dilute H 2 ...
EXTRACTION OF COPPEREXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper. Crashing and Grinding The ore is crushed then ground into powder. CONCENTRATIONFloatation process. The finely crushed ore is suspended in water containing a little amount of pine oil. A blast of air is passed through the suspension. The particles get wetted by the oil and float as a froth .
Cobalt extractionCobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel. They depend on the concentration of cobalt and the exact composition of the used ore. Recovery from coppercobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to ...
Modeling of the Extraction Equilibrium of Copper from ...The extraction equilibrium of copper from sulfate media with the aldoxime Acorga M5640 in ShellSol D70 has been investigated. The distribution results were interpreted by taking into account the nonideality of the aqueous phase. The activity of copper and hydrogen ions in the target systems CuSO ...

Cu (II) extraction from sulfate media by functionalized ...In liquidliquid extraction, copper ions in sulfate medium are extracted by DTMPPA in the same pH range 43. It appears that if the acylpyrazolones such as HTMDDP are efficient to extract copper in the clay, the organophosphorus acids such as DTMPPA are not. However, previous studies showed that immobilized DTMPPA is efficient for zinc extraction whatever the nature of the solid ( Levextrel or ...
Recovery of Copper from Copper Sulfide Concentrate by ... · During sulfate roasting, copper extraction is mainly affected by roasting temperature, roasting time and Na 2SO 3 addition amount. The optimum roasting temperature and time were 500˚C 550˚C and 2 h, respectively. At the optimum conditions, there wasabout 96% of copper leached out. The sulfation promoter Na 2SO 3 only improved the copper extraction at high roasting temperature. It .

ProcessesLeaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SXEW (solvent extraction/electrowinning).
GCSE CHEMISTRYExtraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
