ABSTRACT:
The present invention relates to apparatus for continuous purifying of tin from impurities -- lead and bismuth, by refining.
The apparatus comprises a vacuum chamber accommodating a range of trays arranged in succession and fitted each with an overflow conduit disposed in its side wall at a certain distance from its upper end face, with the overflow conduit communicating with the tray space and being positioned parallel to the tray axis and with the overflow conduit outlet being connected to the underlying tray and a tray column being encompassed with an induction coil establishing a magnetic field under whose effect the metal rotates climbing to the level of the overflow conduit.
