Leaching 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 SX-EW (solvent extraction/electrowinning).

K. NOTES. o Feed concentration: Cu MW = 63.54, so 12 g sulfate/L is (CuSO 4. 5H 2 O MW = 249.6) is close to 3 g Cu/L.. o The feed solutions should be made up by the TA. o If weakly acidic copper sulfate in water is used as feed, less copper will be extracted from the aqueous phase.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

The copper-bearing aqueous phase is advanced to the electrowinning (EW) stage of the process while the barren organic phase is returned to the extraction stage of the process. In the electrowinning stage of the process the copper is reduced electrochemically from copper sulfate in solution to a metallic copper cathode.

the anhydrous copper sulfate, cuso4 molecules has an ionic bond whereas strong acid h2so4 has also a ionic bond. but in case of copper sulfate,It is created between metal cu and non metal so4. because charge of copper cation cu(2+) and charge of sulfate anion so4 (2-) is different. therefore, the results is given ionic bond.

Copper Sulphate Crystallization and MVR. Copper sulphate solution is a product through copper ore leaching and extraction or copper electrolyte purification. The copper sulphate solution can be further treated to copper anode by electro-winning or to copper sulphate crystal. MVR (Mechanical Vapor Recompression) evaporation technology for copper ...

copper extraction with different amount of Na 2SO 3 was shown in Figure 2. Below 500˚C, the increase in roast-ing temperature was found to have a significant effect on copper recovery. When there was no Na 2SO 3 added, copper extraction decreases rapidly above 550˚C due to the decomposition of copper sulfate to other less soluble compounds.

Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction.

The extraction of copper(II) from its solutions containing varying amounts of ammonium sulphate (1–4 M) over a pH range of 2 to 10 using Hostarex DK-16 in kerosene has been studied.Extraction seems to be less at higher pH due to the formation of free ammonia, which subsequently gives rise to non-extractable copper ammine complexes.

Copper sulfate is a term that can refer to either of the following chemical compounds – cuprous sulfate (Cu 2 SO 4), or cupric sulfate (CuSO 4). However, the latter is the preferred compound described by the term 'copper sulfate'.
