Zinc Smelting Gas

  • Zinc Smelting an overview | ScienceDirect Topics

    Due to the lower melting and boiling points of zinc at approximately 420°C (788°F) and 907°C (1665°F), respectively, zinc smelting and converting are conducted at lower temperatures than those of copper, noting that the copper has a melting point at 1085°C (1985°F) and copper concentrate does not melt even at a temperature as high as 1500°C (2732°F) In reductionAt temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide Zinc ores typically may contain from 3 to 11 percent zinc, along with cadmium, copper, lead, silver, andZinc Smelting Assignment Point
