In this investigation, attempts have been made to recover the metallic tin by electrilytic detinning of tinplate scrap. The elctrolysis is carried out with a caustic soda bath. Stainless steel sheets have been used as cathode and the tinplate scrap, packed in the form of rectangular bundles, serves the purpose of the anode. Experiments have been carried out to determine the optimum condition
The tin is dissolved from the scrap and converted to sodium stannate, which is practically insoluble in the caustic soda liquor holding the lead oxide in solution, and goes to the bottom of the bath, together with residual copper and antimony, or their insoluble oxides.

Inside the furnace, the silver soaks up metals like gold, palladium, copper and tin in the e scrap. The molten metal mix is poured into a mold and cooled, and the metals sink to the bottom of the mold, forming a bullion puck. The mold is cracked open with a sledgehammer, and the multimetal puck is removed.
