Results are presented from studies of the intensive radial injection of an air blast into a crucible to recycle electronic scrap. A relation is found to describe the effect of the blast and the unsubmerged air jet on mass transfer, and an empirical formula is obtained to calculate the unit air flow rate in the critical regime.
