Abstract:
A long-lived electrode is produced, for use in the electrowinning of metals, by electrodepositing a coating onto the electrode substrate. The coating has a uniform grain size and structure which is controlled by superimposing alternating current onto direct current during electrodeposition.

Abstract:
Lead is electrowon from aqueous phosphorus-containing fluosilicic acid solution by deposition on a lead cathode, employing an anode comprising a titanium substrate and an electrodeposited lead oxide coating having a uniform, dense grain size and structure.

Abstract:
Lead is recovered from sulfide ores which contain lead by leaching the ore with fluosilicic acid to form elemental sulfur and lead fluosilicate, and then subjecting the lead fluosilicate to electrolysis to produce lead and fluosilicic acid.
Method For Eliminating Solution-Level Attack On Cathodes During Electrolysis
The United States of America as represented by the Secretary of the Interior - Washington DC
International Classification:
C25C 116 C25C 700
US Classification:
204 12
Abstract:
A method for electrolytic deposition of metals, particularly zinc, in which the tendency for the cathode to be attacked in the immediate vicinity of the solution level is eliminated or greatly reduced by positioning a barrier structure in the cell assembly in a manner such that it extends from slightly above to slightly below the level of the solution in the cell. The barrier, which may be of any material resistant to attack by the electrolytic solution, prevents the migration of the oxygen at the solution level and thus protects the cathode from solution level attack.
The Cannes documentary prize ( LOeil dOr) was shared by Oscar nominee Raoul Pecks Ernest Cole: Lost and Found and The Brink of Dreams, directed by Ayman El Amir and Nada Riyadh. This gives both films a leg up heading into this years documentary race. Ron Howards excellent Cannes selection
