Abstract
Disclosed is a pyrometallurgical reactor for entraining a low density particulate solid (e.g., coal) in a high density liquid (e.g., slag) in order to promote and accelerate reactions dependent upon contact between the solid and the liquid. The present disclosure develops interrelationship between the dimensions and rotation rate of a mechanical stirrer and the dimensions of the reactor vessel in order to achieve, simultaneously, good entrainment of the particulate solid which is delivered to the surface of the liquid, minimal entrainment of gasses along with the particulate solid, and minimal erosion of the vessel walls.
