Abstract
A series of eight tests utilizing byproduct slags from blast furnaces, copper and lead smelting operations, and phosphate operations has shown that satisfactory material for subsequent spinning operations to produce mineral wool can be prepared in an electric arc furnace. No significant differences in furnace operation, energy consumption, or product weights were noted as a function of charge particle size. Unlike standard cupola furnace operations, coke is not required. The product slags were suitable for mineral wool production with respect to liquidus temperature, acid/base ratio, and viscosity. The small amount of coproduct metal is not suitable for use in the ferrous metal industry because of high phosphorus, sulfur, and copper contents. However, this metal might find application as a source of metallic iron for cement copper production with proper preparation.
