Abstract
This disclosure relates primarily to the recovery of hydrogen-reduced metals from aqueous solutions of salts thereof, such as, for example, copper from copper sulphate solution, by hydrogen reduction at a catalytic barrier made pervious to the solution, in an apparatus provided with means to supply hydrogen along a face of said barrier at which the aqueous solution is applied to effect deposition thereupon and flowing the solution transversely through the barrier to continue deposition upon the other face of the barrier.
Claims17
A process for recovering hydrogen-reduced metals or ions from an aqueous electrolyte solution thereof, that comprises, providing a catalytic barrier having openings distributed therethrough to render said barrier pervious to said solution, applying hydrogen to said barrier and flowing the solution transversely through the barrier openings while contacting both surfaces of said barrier by the solution.
Apparatus for recovering a hydrogen-reduced metal from an aqueous solution of an ionized salt thereof having, in combination, a hydrophobic catalytic barrier having electrical conductivity along at least parts of the same and provided with openings distributed therethrough of size sufficient to render the same pervious to said solution in addition to being otherwise hydrophobic;
- and means for flowing hydrogen and said solution in mixed phase along one surface of said barrier and forcing the same transversely through the barrier openings further to flow turbulently along the opposite surface of said barrier.
Apparatus for recovering from aqueous solutions hydrogen-reduced metals and for similar uses, comprising a hydrophobic catalytic barrier electrically conductive along at least parts of the same and provided with openings distributed therethrough of size sufficient to render the same pervious to solutions and otherwise being hydrophobic.
