Tetronics A process for treating dusts from electrical arc furnaces for making steel and nonferrous metals. Volatile metals (zinc, lead, cadmium) are recovered, and residual slag is nontoxic and suitable for landfill. The dusts, mixed with coal dust and a flux, are fed to a furnace heated by a plasma gun. The metal oxides present are selectively reduced and the vapors of zinc, lead, and cadmium are condensed in a modified Imperial Smelting furnace. Developed by Tetronics Research Development Company, United Kingdom, and first commercialized for steel dusts at Florida Steel, Jackson, TN, in 1989. Seven plants were operating in several countries in 1992. [Pg.267]

Britannia Refined Metals Ltd. (BRM) is a wholly owned subsidiary of MIM Holdings Ltd. and operates within the MIM (Europe) group that also includes Britannia Zinc Ltd. (BZL), MIM Huttenwerke Duisberg (MHD) and Britaimia Recycling Ltd. (BRL) at Wakefield, in Yorkshire. The BRM site is located on the south bank of the River Thames, 35 km east of London. There is a deep-water jetty adjacent to the plant where the crude lead fi om Mount Isa and the Imperial Smelting Furnace bullion from Duisberg are unloaded and stored. [Pg.346]

In 1960 the first standard commercial scale Imperial Smelting Furnace (ISF) was constructed at Swansea in the UK, as an adaptation of the lead blast furnace, to simultaneously produce zinc and lead. The furnace operated with a hot top to retain zinc in the vapour phase. The top was sealed and gases passed through a lead splash condenser to strip zinc from the gas phase into a lead-zinc bullion which could be cooled for separation of crude zinc and lead metals. The ratio of zinc to lead production from these units is generally more than 2 1, and lead production from the standard unit is close to 40 000 t/a. Thirteen plants were constructed around the world but due to unfavourable economics a number of these have now closed. Details are given in Chapter 6. [Pg.23]

The Imperial Smelting Furnace (ISF) was primarily developed as a blast furnace for the production of zinc. It relies on the concept of reducing zinc oxide in a shaft furnace to produce zinc vapour in the furnace gases. By maintaining high temperatures at the top of the shaft reversion to zinc oxide can be prevented. The hot furnace gases are ducted from the furnace to a condenser where they are chilled using a spray of molten lead at around 500°C, which condenses and absorbs the zinc from the gas stream. This concept requires close control of furnace gas composition and a sealed top furnace. [Pg.89]

The copper to sulfur ratio is important and with bullions low in sulfur content, such as from the Imperial Smelting Furnace, copper dross has a high content of metallic copper. The precipitated copper compounds are less dense than lead and float to the surface as a voluminous dross and are skimmed off. A significant amount of lead is entrained in the dross and further processing is useful to separate and recycle the entrained lead and yield a copper matte suitable for sale to a copper smelter. [Pg.200]
