REFINING OF BLISTER COPPER
Blister copper is refined by an electrolytic process. Blister copper in the form of a large plate is made as anode. A thin plate of pure copper is cathode. A solution of CuSO 4 is used as an electrolyte. The impure blister copper dissolves at the anode. During electrolysis pure copper is deposited in the form of pure copper at the cathode.learn more
Whatever method is used to manufacture copper from its ore, its final purification is by electrolysis (Figure 6). Slabs of impure copper (blister copper), together with thin sheets of pure copper metal or stainless steel or titanium are immersed in a solution of copper(ll) sulfate ( mol dm3) and sulfuric acid (2 mol dm3). The pure copper ...learn more
copper: Commercial Preparation | Infoplease
The resulting copper is 98% to 99% pure; it is called blister copper because its surface is blistered by escaping gases when it solidifies during casting. Most copper is further purified by electrolysis . The blister copper is refined in a furnace and cast into anodes. Thin sheets of pure copper .learn more

07 02 OCCURANCE AND PRINCIPLES OF COPPER ZINC .
shape of blisters to the surface of copper, which is therefore, known as Blister copper. • Purification: i. Poling: The blister copper is purified by melting it in a reverberatory furnace where it is exposed to an oxidising atmosphere. The impurities are expelled as volatile oxides. During this process the molten mass is stirred with long ...learn more
Poling (metallurgy) Wikipedia
Poling is a [metallurgical] method employed in the purification of copper which contains copper oxide as an impurity and also in the purification of tin ("Sn") which contains tin oxide (stannic oxide or "SnO 2") as an impurity. The impure metal, usually in the form of molten blister copper, is placed in an anode furnace for two stages of refining.learn more
Refining Process Against Impurities | Oil Refining Process ...
Refining Process Against Impurities. ... For example copper is purified using this method. ... Vapour phase refining: In this type of purification, the metal should form a volatile compound in the presence of a reagent and it should easily decompose in order to recover the metal. The metal is transformed into its volatile compound.learn more

Extraction of copper from copper pyrites (CuFeS2 ...
The molten copper is poured out and allowed to cool. The sulphur dioxide escaping from the melt gets trapped in the cooler parts of the surface giving a blistery appearance for copper and hence it is called blister copper. Blister copper is further refined by poling and electrolytic method, as described in the refining of metals.learn more
Primary Copper Smelting
Impurities in blister copper may include gold, silver, antimony, arsenic, bismuth, iron, lead, nickel, selenium, sulfur, tellurium, and zinc. Fire refining and electrolytic refining are used to purify blister copper even further. In fire refining, blister copper is usually mixed with flux and charged intolearn more
