Recovery of silver from polymetal nitrate solution by means of rotating film pertraction technique was studied. Silver was successfully separated from the accompanying metals, viz. copper, zinc and nickel, using as a membrane phase a 0.06-M solution of tri-isobutylphosphine sulfide (TIBPS) in n-octane and an aqueous ammonia solution as a stripping phase. After 4 h of continuous contacting silver was practically completely extracted from the feed and transferred into the strip solution, while the other three metals remained unextracted.
