Abstract:
An apparatus for recovering platinum group elements comprises a furnace body having an interior space substantially shot off from external air, a material charging port and an exhaust port provided in an upper half of the furnace body, at least two fluid discharge ports provided in a lower half of the furnace body at different height levels. a material charging chute connected to the material charging port. an exhaust unit connected to the exhaust port; and electrodes for passing electric current through and heating material charged into the furnace. The material charging chute is equipped with a vertical two stage shutter so as to maintain airtightness when material is charged into the interior space of the furnace.
