Imperial smelting process

As of 1992, eight smelters used the Imperial smelting process (Fig. 4), but none within the United States. The essential reactions taking place for smelting are... [Pg.36]

In the recovery of cadmium from fumes evolved in the Imperial Smelting process for the treatment of lead—zinc concentrates, cadmium is separated from arsenic using a cation-exchange resin such as Zeocarb 225 or Ambedite 120 (14,15). Cadmium is absorbed on the resin and eluted with a brine solution. The cadmium may then be recovered direcdy by galvanic precipitation. [Pg.387]

ISP (Imperial Smelting Process)—a combined lead-zinc process in which oxidized concentrates are reduced with coke in a shaft furnace and the zinc vapor collected in a lead splash condenser. [Pg.1774]

Imperial smelting process. This process is identical to the combination previously described of roasting, sintering, and smelting, except for the fact that it is performed on complex lead-zinc ores to produce simultaneous zinc and lead metals. In the blast furnace, a mixed lead/zinc sinter is added and the lead bullion is tapped conventionally from the bottom of the furnace while metafile zinc vapor is distilled off and captured by a spray of molten lead droplets. This cool zinc can be floated off, while the lead is recirculated to the collector. [Pg.200]

For feed to the Imperial Smelting Process, there can be penalties on silica, as well as arsenic, bismuth and antimony. [Pg.38]

The Imperial Smelting Process (ISP) technology is a modified variant of the conventional shaft furnace process, that is particularly suited to the treatment of bulk lead-zinc concentrates. The IS process was developed in the late 1950s by Commonwealth Smelting Ltd at its Avonmouth plant in... [Pg.43]

The second possibility available to some producers is to use Imperial Smelting Process (ISP) technology, which is able to produce both lead and zinc mainly from mixed concentrates and relatively low grade feed. This is a relatively cleaner form of conventional smelting that is tried and tested, which uses relatively cheap raw materials and which benefits from co-product revenues. There has recently been a revival of interest in this technology. [Pg.241]
