This invention relates to an improved method for processing high zinc iron ores for production of iron and steel comprising the steps of; producing agglomerate comprising a mixture of iron oxides, carbonaceous materials, and fluxes with mean-particle size respectively of 35 to 70, 25 to 60, and 45-85 microns, to form agglomerates of 8 to 15 mm size using combination of organic and inorganic ...
Lead and Zinc Smelting - IFC
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-

Lead and Zinc - Energy.gov
The zinc oxide (ZnO) and lead oxide in the slag are reduced, and the metallic zinc and lead are volatilized. As the metallic vapor exits the furnace, it is oxidized, forming particles of zinc oxide and lead oxide. The particulate is recovered in a baghouse and sent to a zinc refinery for zinc recovery.
Reclamation of lead/zinc processing wastes at Kabwe, Zambia
sulphide ore averages about 12% lead, 34% zinc and the silicate 8%, lead and 23% zinc. In 1977, ore reserves were 2.40 million tonnes.4 About 25 minerals were extracted by underground mining; ores contained principally large amounts of lead and zinc and lesser quantities of silver and cadmium.4 All mining activities officially ceased in 1994.
