In the fumace/ketde batch process, a charge of drossed blast furnace buUion is treated in a reverberatory furnace or a kettie (see Fig. 12). Oxygen is supphed in the form of compressed air or as lead oxide blown into the bath through submerged pipes. The formation of lead oxide serves by mass action to assure the removal of the impurities to the desired low concentrations. The softening reactions are... 

Reaction With Sulfur. An important use of calcium carbide has developed in the iron (qv) and steel (qv) industries where the carbide has been found to be an effective desulfurizing agent for blast-fumace iron. Calcium carbide and sulfur present in the molten metal react...

The bismuth oxide concentrate are rarely little on the ore production, so the materials of the reducing smelt are the bismuth oxide dross attained from the oxidizing smelt of the lead or copper anode slime[19,20,21],the bismuth oxychloride enriched from the blast fumace[22], the copper converter flue dust[23], and so on.
