Smelting - an overview | ScienceDirect Topics

The furnace is computer controlled to give a specified concentrate smelting rate while producing matte and slag of desired composition and temperature. Matte/slag temperature is sensed by thermocouples embedded in the furnace walls (MacLeod, Harlen, Cockerell, & Crisafulli, 1997). It is controlled by adjusting the rate at which fossil fuel is ...

Secondary Lead Smelting Background Information Document ...

Lead casting is not a substantial source of emissions because the molten lead is well below the fuming temperature of lead. Total uncontrolled metal HAP emissions from all process fugitive sources at a typical smelter may be from 7 to 30 Mg/yr (8 to 32 tpy), depending on smelter capacity. ...

Lead smelting - Wikipedia

Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting.
