The objectives of this study were to assess the need for small-scale detinning technology suitable for municipal solid waste (MSW) ferrous scrap and to determine the technical feasibility of various processes that might meet this need. A comprehensive review of existing detinning processes for tin-plated steel was made, and new concepts on small-scale detinning technology were reviewed. Economic evaluations of processes and concepts when adapted to MSW magnetics were undertaken. The principal findings of the study were as follows: (1) conventional detinning technology is not adequate to process MSW magnetics on a small scale; (2) it is unlikely that nonupgraded MSW magnetics can be detinned economically; and (3) if the MSW magnetics are upgraded to nearly eliminate nonmetallic tramp materials, they can be detinned on a small scale economically by a number of processes with modifications to treatment vessels including alkali chemical oxidation, acid chemical oxidation, and alkali electrolysis.
