Electrolytic Copper Refining Tank: the anodes of impure copper are refined by electrolytic means to the pure cathode copper in the refining tank. It is filled with a solution of sulfuric acid and copper(II) sulfate, in which the anodes and cathodes are interleaved and immersed — between anodes are suspended starting sheets which are thin sheets of electrolytic copper.
The process for electrorefining copper is typical of those carried out in aqueous solution. The electrolyte is copper sulfate (0.7 molar) and sulfuric acid (2 molar) and the way in which the purification of the copper occurs can be seen by considering the metals likely to be found. as impurities :
Copper electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H2SO4, and selectively electroplating pure copper from this electrolyte without the anode impurities.

The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.
Forty-four anodes are hung by their ‘handles’ in a large, rectangular tank containing a liquid electrolyte made of sulfuric acid and copper sulfate. The Amarillo refinery houses 2,400 of these tanks in a single building covering more than 11 acres.Forty-five pure copper sheets suspended on solid copper bars are inserted into the same tank
Copper refining: Hydrometallurgy. In hydrometallurgy, copper concentrate undergoes refining via one of a few processes. The least common method is cementation, in which an acidic solution of

Melting and Refining Technology for Copper Produced from Scrap Charge Our copper refining technology allows the use of higher-impurity charge materials, and still produce premium quality refined copper. In some applications, copper produced by this method may compete with copper that underwent electrolytic refining.

Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or
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).
Silver refining in acid is very simple, requires almost no investment in time, equipment or supplies and it can be done by almost anybody. However, it requires the use of concentrated acid and the fumes it produces are very corrosive. Therefore, it must be done out-of-doors, protective clothing should be worn and reasonable care must be taken.
In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.
Refining; Smelting. The Oxygen Flash Furnace At the Asarco copper smelter in Hayden, The Acid Plant Sulfur dioxide gas from the flash furnace is captured and combined with water in an adjacent acid plant to produce sulfuric acid.The acid is sold as a by-product to
To do so, raw copper is electrolysed in a copper sulfate solution. The raw copper is used as the anode. Here, the ignoble elements and copper will dissolve. At the cathode (also made from copper), pure copper is deposited. In this experiment, the copper refinement is conducted using a brass electrode (copper, "contaminated" by sinc).
These have a pure copper cathode, on which copper is deposited (Eq. 13.20), and a lead anode, rather than the copper anode used in electrorefining. The lead anode reforms sulfuric acid from the hydrogen ions released from water, instead of contributing dissolved lead to the electrolyte ( Eq. 13.22 ).
