ABSTRACT:
Materials of low electrical conductivity, such as minerals and metal compounds, are floated on a metal melt which is itself heated by a channel-type electric inductor, the heat from the melt transferring to the material. A pneumatic blast is injected into the melt so that the interface between it and the material is caused to dynamically undulate, promoting the heat exchange from the melt to the material. The blast can carry particles of additive or reactive agents.
