A typical flowsheet of lead-zinc smelter  Imperial Smelting Furnace (ISF) is also called zinc blast furnace which was developed for mixed zinc-lead ores. Charges to the furnace are lump sinter, hot briquettes, and coke. Slag and lead are continuously tapped from the bottom of the furnace into a forehearth where separation :// This book includes sections on the general historical context of zinc extraction as well as electrolytic process and carbothermic reduction processes. Aspects of major zinc production including costs and energy consumption are also covered in this general reference volume. Zinc Smelting Industry Perspective and Introduction 2. Historical Lead and Zinc Smelting Industry Description and Practices Lead and zinc can be produced pyrometal-lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet-allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra- In inhalation studies, guinea pigs and rats were exposed for 3 hours and rabbits for 2 hours by head and nose exposure to zinc oxide fume (ultrafine particles: median diameter µm, mass median diameter µm) in zinc oxide concentrations of and 5 mg/m 3 (Gordon et
Smelting of Lead. The conventional process for smelting lead involves roasting a mixture of lead sulfide concentrate and flux on a sinter machine, followed by blast furnace smelting.

Zinc is the 23 rd most abundant element in the earth's crust. Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc is necessary to modern living, and, in tonnage produced, stands fourth among all metals in world production - being exceeded only The PbZn symposium series book is considered the leading international technical forum for the lead and zinc processing industries. The PbZn volume addresses all aspects of current processing technologies for primary and secondary lead and zinc, as well as emerging › Materials › Special types of Materials.
