摘要

1533728 Detinning scrap metal M & T CHEMICALS Inc 29 June 1976 [30 June 1975] 13300/78 Divided out of 1533727 Heading C7B Tin scrap is supplied to a perforated rotating cylindrical anode 20 containing a helix 27 by a vibrating storage hopper and shoot 11 wherein it is in electrical contact with a caustic alkali solution and cathodes contained in tank 24 in which the rotating anode is located. The tin is removed from the scrap metal and departs on the cathodes. The detinned scrap is passed through the helix of the anode and is discharged from the exit end of the cylindrical anode, washed and passed to a discharge conveyer for collection.
