Electrorefining uranium in a chloride electrolyte / By R. E. Campbell, Thomas A. Sullivan, Lawrence Radiation Laboratory. and United States. Bureau of Mines. Abstract. Performed in cooperation with the Lawrence Radiation Laboraory, University of graphy: p. Mode of access: Internet. ELECTROREFINING IN AQUEOUS CHLORIDE MEDIA FOR RECOVERING TIN FROM WASTE MATERIALS Tamas Kekesi1)* 1) the hydrochloric acid tin chloride electrolyte solutions can be applied. The major The main characteristics of tin electrorefining are strongly dependent on the type of solution. tion needs uranium chloride, UC13, which is hard to be obtained. (2) Electrorefining with Solid Iron Cathode After the fuel elements are dissolved, uranium is transported to a solid iron cathode. By imposing an anode potential that is less than the oxidation potential of cadmium, uranium and plutonium are predominantly. The energy saving potential and refining capabilities of three copper(I)/electrolyte systems for electrowinning copper were compared experimentally. The alternative electrolyte systems studied were copper(I)/acidic chloride, copper(I)/acetonitrile and sulfuric acid, and copper(I)/ammonia solutions. These were compared to the conventional copper(II)/sulfuric acid by: 3.
In electrolytic refining, the plates of crude metal are anodically dissolved in a suitable electrolyte, while “pure” metal is deposited on the adjacent cathodes. The electrorefining process was introduced about a hundred years ago to produce a substitute to fire-refined by: The main step in the pyrometallurgical process is molten salt electrorefining , where the actinide elements are recovered and decontaminated from the fission products. Figure 1 shows a schematic flow of the normal operation of this electrorefining step. Electrorefining. Electrorefining is a process in which materials, usually metals, are purified by means of an electrolytic cell.

Aqueous electrorefining — The conditions used for the refining of five metals are summarized in Table The electrolyte and other conditions must be selected so that both the anodic dissolution and the deposition of the metal occur with high efficiency while none of the impurity metals can transfer from the anode to the Size: KB.
The Electrorefining and winning of copper: proceedings of the symposium sponsored by TMS Copper, Nickel, Cobalt, Precious Metals, and Eletrolytic Processes Committees, and held at the TMS th Annual Meeting in Denver, Colorado, February , Metallurgical Society of American Invitational Mathematics Examination Conference Proceedings. Electrolyte additives used by Palabora are glue, thiourea, Avitone and chloride. Their effects were determined on cathode quality, the size of the current density region that gives the desired compact morphology, and current efficiency. This was done in a small-scale cell. Small cells have different hydrodynamics from industrial-scaleFile Size: KB. A buildup of material at uranium anodes during uranium electrorefining in molten chloride salts has been observed. Potentiodynamic testing has been conducted using a . The purpose of the electrorefining is to separate uranium from the other fuel components. Once the FDBs loaded with chopped fuel segments are inserted in the molten salt electrolyte, the bond sodium and active metal fission products chemically react and displace UCl 3 from the molten salt. Uranium in the fuel segment is electrochemically.
