Blast Furnace Slag

Fuming of lead blast furnace slag is an important source of zinc oxide as feed for zinc electrowinning. Slag containing 1218% zinc is reduced in a water-jacketed furnace at 11501200°C by injection of pulverized coal and air through tuyeres. Zinc metal vapor is reoxidized to ZnO above the bath, and collected in a baghouse.

Fuming of Zinc from Lead Blast Furnace Slag |

Abstract. Zinc oxide activities in a typical lead blast furnace slag have been calculated from plant operating data. These activities were used to assess the probable effect of fuel composition, oxygen enrichment, and air preheating on the efficiency and capacity of the slag-fuming operation.
