Abstract
This disclosure concerns primarily the recovery of hydrogen-reduced metals from aqueous solutions of salts thereof, by hydrogen reduction at a porous hydrophobic catalytic barrier, at ordinary temperatures, in an apparatus provided with means to supply hydrogen to one face and aqueous solution to the other face of said barrier.
Claims25
A process for recovering hydrogen-reduced metals or ions from an aqueous solution of an ionized salt thereof, that comprises, providing a porous hydrophobic catalytic barrier, contacting one surface of the barrier with said solution, and applying hydrogen gas to the other surface, thereby to produce the hydrogen-reduced mtals or ions at said one surface.
A process for recovering hydrogen-reduced metals or ions from an aqueous solution of an ionized salt thereof that comprises, providing in contact with the solution a porous hydrophobic catalytic barrier, and flowing hydrogen gas upon the catalytic barrier to reduce metals or ions from said solution at surface portions of the catalytic barrier contacting the solution.
