    • PURPOSE: A method of recovering catalytic metals from fluid compositions containing catalytic metal colloids using a porous metal filter is provided. CONSTITUTION: The method comprises the processes of (a) concentrating catalytic metal colloids as a precipitate on a porous metal filter; then (b) removing the precipitate from the porous metal filter by backwashing the precipitate with a fluid; then (c) solubilizing the precipitate to form a solution; and then (d) retrieving the catalytic metal from the solution, wherein greater than 90% by weight of the catalytic metal is recovered from the fluid, wherein the catalytic metal comprises copper, beryllium, aluminum, tungsten, tellurium, nickel, silver, germanium, molybdenum, selenium, rhodium, osmium, iridium, ruthenium, lead, magnesium, gold, platinum, palladium, or mixtures thereof, wherein the catalytic metal comprises from about 0.0001% by weight to about 0.05% by weight of the fluid, wherein the catalytic metal colloid is solubilized with an oxidizing agent, wherein a terminal pressure ranges from about 40 psi to about 125 psi. The method of recovering catalytic metal from a drag out bath comprises the processes of (a) concentrating catalytic metal colloids as a precipitate on a porous metal filter; then (b) removing the precipitate from the porous metal filter by backwashing the precipitate with a fluid; then (c) solubilizing the precipitate to form a solution; then (d) contacting the solution with an adsorbent to retrieve catalytic metal ions on the adsorbent; and then (e) retrieving the catalytic metal from the adsorbent by contacting the adsorbent with a buffer.
