Zinc: smelting, producing and classification-Metalpedia

Preheated air at 190 to 1,050 C (370 to 1,920 F) is blown into the bottom of the furnace. Zinc vapour and sulfides leave through the top and enter the condenser. Slag and lead collect at the bottom of the furnace and are tapped off regularly. The zinc is scrubbed from the vapour

Zinc Ore - an overview | ScienceDirect Topics

Vertical retort has a much higher capacity than horizontal retort. The vertical retort developed by the New Jersey Zinc Co. is made of silicon carbide and has the shape of a rectangular shaft 10–15 m (33–50 ft) high and 2 m (6.6 ft) long. The retorts are heated from the outside, and a number of retorts are separated by combustion chambers that form a battery, in the same way as in a coking plant (Rosenqvist, 1974). Most vertical retorts

Zinc Smelting - an overview | ScienceDirect Topics

The major processes currently used in the world to smelt zinc include the blast furnace process, ISP, electrolytic and electrothermic (St. Joseph Mineral Company), and vertical retort. Horizontal retort is not commonly used anymore ( Sinclair, 2005 ). Fig. 3.7 presents the major steps of the extraction of zinc

Over 95 percent of the zinc vapor leaving the retort is condensed to liquid zinc. The carbon dioxide is regenerated with carbon, and the carbon monoxide is recycled back to the retort furnace. 12.7.3 Emissions And Controls Each of the 2 smelting processes generates emissions along the various process steps.
