Abstract
A method for refining a quantity of metal by a correlated quantity of fluid slag comprising discharging the metal to be refined as a stream into a refining vessel and discharging the slag into the vessel in a stream which strikes the metal stream. The slag is discharged in an amount equal to 50% of the total slag content before the discharge of 20% of the metal is completed, the discharge of slag being halted while continuing the discharge of the metal until 50% of the metal has been discharged. The discharge of the remaining 50% of the slag content is resumed as a stream striking the metal stream during the time when the remaining 50% of the metal is discharged.
