An example where copper is further purified is at the Asarco electrolytic plant in Amarillo, Texas. The 99% pure copper from the anode furnace is cast into 750pound, 3inch thick, rectangular slabs called anodes. The final step is a process called electrorefining.

The blister copper is already virtually pure (in excess of 99% copper). But for today's market, this is not really pure enough! It is purified further using electrolysis. This is known as electrolytic refining. The blister copper is cast into large slabs which will be used as the anodes in the electrolysis apparatus (see page 4). The electrolytic refining of copper produces the high quality, high purity copper required by .

A blister copper anode plate, which contains –% copper, is dissolute during the electrolytic refining process of copper in the CuSO 4 –H 2 SO 4 electrolyte system. Dissolution reactions of metals such as Fe, Ni, Pb, As, and Sb, and precipitation reactions of Au and Ag occur on the anode.

Copper electrorefining (CuER) is the principal method for producing >70% of high or % pure copper cathodes from 9799% pure blister/fire refinedscrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge, other soluble impurities, particularly the metalloids (group VA/15 elements or Q: As, Sb and Bi) and some transition metals (Mt) codissolved with Cu(II).

electrolytic refining. In firerefining, molten blister copper is placed in a firerefining furnace, a flux may be added and air is blown through the molten mixture to remove residual sulfur. Air blowing results in residual oxygen which is removed by the addition of natural gas, propane, ammonia or wood. The fire

Electrolytic refining. The purest copper is obtained by an electrolytic process, undertaken using a slab of impure copper as the anode and a thin sheet of pure copper as the cathode. The electrolyte is an acidic solution of copper sulphate. By passing electricity through the cell, copper is dissolved from the anode and deposited on the cathode. However impurities either remain in solution or collect as an insoluble .

There are numerous viable approaches to the treatment of anode slimes from electrolytic copper refining. Of particular interest in the treatment of slimes are the behavior and recovery of selenium. The understanding of the process chemistry involved in the treatment of anode slimes should be aided considerably by recent work on the formation and characterization of slimes.

Copper refining (Main article electrolytic refining of copper) Copper refining in it self is a process usually conducted in large copper plants to get economy in scale. For a refiner the main reason to run a copper cell is to recover precious metals contained in copper, for example from smelting where copper can be used as a collector metal.
