ABSTRACT:
Gases are removed from particles, such as ferrochrome, by providing a container having an open top and a vertical wall having closely spaced opening therein so constructed that the particles will not plug or pass therethrough. Preferably a central vertical tubular member is provided in the container with similar holes. The particles are placed in the container between its wall and the vertical member and heated in a furnace to a temperature at which the gases will evolve. The gases may be removed by having the furnace under vacuum or by the atmosphere in the furnace.
