ABSTRACT:
A plasma furnace including an upper chamber having three electrodes radially spaced from an ore feed tube. The ore is gasified by a plasma arc in a central crucible and allowed to condense in the space between the central crucible and an outer crucible. The outer crucible forms the boundary between the upper chamber and a lower chamber. The lower chamber is filled with molten copper which acts as a filter. Since there is no agitation in the lower chamber, molten ore entering from the upper chamber separates between a fraction containing heavy metals which is drained from a sump, and a fraction containing lighter materials which is decanted through an overflow tube.
