Abstract

A substantially dry and dust free method of recovering ladle slag is allowing hot ladle slag to cool to powder form in a controlled environment and collecting the powder in a receiver therefor. A vessel having a chamber containing in an upper portion a screen through which ladle slag can pass into a receiver below and means for cooling the slag in the vessel are provided.
