electrorefining

[i¦lek·trō·ri′fīn·iŋ]
(chemical engineering)
Petroleum refinery process for light hydrocarbon streams in which an electrostatic field is used to assist in separation of chemical treating agents (acid, caustic, doctor) from the hydrocarbon phase.
(metallurgy)
Purifying metals by electrolysis using an impure metal as anode from which the pure metal is dissolved and subsequently deposited at the cathode. Also known as electrolytic refining.

Increasing production in copper electrorefining by means of the Isa process has been discussed by Sako et al(55).
The key unit processes of pyroprocessing are the electrolytic reduction (also called oxide reduction (OR)) and the electrorefining (ER) [1-8].
(40) Pyroprocessing is also referred to as "electrorefining" or "dry" processing, as opposed to "wet" or "aqueous" conventional processing with water-based chemicals.
In Session 3, Molecular Recognition Technology (MRT) during copper electrorefining and electrowinning was reported to have removed impurities such as bismuth, antimony, iron and chloride from the electrolyte, and cobalt was recovered from barren solution.
The electrorefining and electroplating processes may be put on a firm scientific basis today.
III Electrorefining and Hydrometallurgy of Copper; and Vol IV the Pyrometallurgy of Copper.
Normally it is advantageous to treat oxide ores and concentrates by leaching/EW rather than smelting and electrorefining. On the other hand treating copper sulphide ores by flotation and smelting is cheaper than roasting, leaching and EW.
Volume III covers Hydrometallurgy and the Electrometallurgy of Copper, under the following headings: leaching of copper minerals-theory and practice (5 papers); bacterial leaching and leaching of tailings (5 papers); separation and recovery processes (5 papers); impurity control and by-products (8 papers); copper electrorefining, cathode substrates and anode passivation (9 papers); electrorefining tankhouse operations and modernisation (9 papers); copper electrowinning (3 papers); and copper refining developments (6 papers).
