A recirculating system for ingestion of metal scrap into a molten melting media is disclosed. The system comprises a heating bay containing the molten melting media and a scrap charging bay having upper and lower portions wherein metal scrap is charged into the upper portions of the bay and ingested into the melting media, the scrap charging bay connected to the heating bay to permit molten melting media to be circulated from the heating bay through the scrap charging bay and back to the heating bay. An impeller is positioned in the scrap charging bay for purposes of ingesting the metal scrap into the molten melting media. The impeller has a base member and a top member provided with an opening therein and having an annular flange thereon extending beyond the periphery of the base member substantially transversely to the impeller rotation axis, the impeller having blades positioned between the base member and the top member, the blades extending in a generally radial direction.

A method for feeding a subliming material into a liquid is disclosed, by which the end of a pipe is submerged below the surface of the liquid, and a subliming, particulate material is propelled through the pipe and into the liquid by a flow of gas. The flow rate of the entraining gas is sufficient to prevent the formation of deposits on the interior walls of the pipe by countercurrent gaseous diffusion of the subliming material.
