ABSTRACT:
Phosphorus furnace slag and ferrophosphorus are separated from one another. To this end, a mixture of phosphorus furnace slag and ferrophosphorus, which is tapped off periodically from a phosphorus furnace, is introduced into a separating zone fitted with a bottom outlet and an overflow, through which the phosphorus furnace slag floating on the ferrophosphorus is delivered to a solidification zone. The separating zone has the dimensions necessary to receive the quantity of ferrophosphorus tapped off, which is allowed to remain therein for a period between 0.25 and 2 hours, so as to complete the separation of the phosphorus furnace slag by allowing it to solidify above the liquid ferrophosphorus. Liquid ferrophosphorus is finally discharged through the bottom outlet in the separating zone and delivered to a solidification zone.
