 VMP-1750 is a customized furnace for recovering valuable metals from oxide slags. It combines induction heating and reverse-polarity transferred Arc Plasma together in a high vacuum chamber.   The induction heating will melt slags in a graphite crucible,  and  water cold anode electrode will produce a high-temperature plasma to separate noble metals from oxide slag by electrolysis.

SPECIFICATIONS:
 Vacuum Chamber
  • Stainless steel vacuum chamber ID Ø315 mm × 315 mm H
  • Water-cooled SS chamber for prolonged melting time 《= 3 hrs.
  • Ø120 mm quartz observation window. 
  • DN160 ISO-K port for connection with a turbo pump
  • KF40/25 port for connection with a rough pump
  • 1/4" gas inlet and bleed valve as a gas outlet
  • Pressure safety relief valve @ 3 psig
Induction Heater

Graphite Crucible 

  • Two graphite crucibles are included
    • Graphite crucible 1: Ø47 OD × Ø35 ID × 88 H mm; working volume ~70 ml (up to 400g Fe alloy) 
    • Graphite crucible 2: Ø75 OD × Ø60 ID × 105 H mm; working volume ~250 ml (up to 1200g Fe alloy)
  • One water-cooled copper electrode is connected to the graphite crucible on the bottom as cathode.

Arc Generator and Electrode
