  • Recent developments in slag-fuming - EPrints

    lead smelter, about 6000 tons of slag are also expected to be produced. In 1905, the lead metallurgists started investigations with a view to recovering zinc from lead blast furnace slag. In earlier attempts, the idea of reducing zinc oxide to metallic zinc and then to fume was abandoned after trying compressed air blast without fuel. In 1925

  • Lead and Zinc - Energy.gov

    Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

    After the reduction has been completed, the molten slag and lead are taken out of the furnace hearth at a temperature that is approximately equal to the melting point of the slag. The slag runs over the top into a granulation system and is water quenched, granulated, and discarded. Metal values in the slag include approximately 5% zinc and 0.5%

  • Zinc: smelting, producing and classification

    Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from the other minerals. Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible. Zinc

  • LEAD ZINC EXTRACTION PROCESSES - EPrints

    Ores with a mixture of lead and zinc concentrate usually have lower respective metal concentrations. During sintering, a blast of hot air or oxygen is used to oxidize the sulfur present in the feed to sulfur dioxide (SO2). An increasing proportion of the supply of both metals (over 50% for lead and 30% for zinc) is being met by recycling.
