The alloy content in the slag is substantial and comprises typically 1% to 4% of the total alloy tapped. It is therefore normally viable to attempt recovery of this alloy from the slag. The most common recovery process is to crush the slag (in the case of the first slag-handling method) and recover the alloy particles in a wet jigging process.
