A method of manufacturing spheroidized beads comprising the steps of introducing raw ore particles in the presence of an inert non-oxidizing carrier gas to a carbon arc plasma flame assembly to which is fed a controlled amount of oxygen and argon gas, melting the ore particles to form spheroidized droplets thereof, allowing the spheroidized droplets to fall by gravity in a substantially closed chamber having a controlled atmosphere wherein the droplets cool and solidify into beads, and collecting the beads.
