Tin Removal from Tinplate by Sulfurization

Naoki Tokumitsu; Hiroyuki Katayama

Results of the laboratory scale experiments for the removal of tin from tinplate are described. It is found that tin coated layer of tinplate was removed when it was exposed in the sulfurizing atmosphere in adequate temperature range (400-500 degree centigrade) and time. Based on the test results, an process image of dry detinning of steel can waste is proposed.
