Fluxing lime

Fluxing lime is lump or pebble quicklime used as flux in steel (qv) manufacture the term may also be appHed more broadly to include fluxing of nonferrous metals and glass (qv). It is a type of chemical lime. [Pg.164]

Calcium Oxide (lime, Quicklime, Burnt Lime, Calx, Unslaked Lime, Fluxing Lime). CaO, mw 56.08, white or greyish-white lumps or powd, mp 2580°, bp 2850°, d 3.25-3.40g/cc. SI sol in w with formation of calcium hydroxide and evolution of large amts of heat sol in acids, and insol in ethanol. Coml prepn consists of heating calcium carbonate in kilns at 1000—1100° until all of the C02 is driven off. Lab prepn is by burning calcium carbonate or calcium oxalate at about 800° using a quartz crucible in an electric furnace... [Pg.450]

This is typified by the Varta process implemented by Varta Batterie AG at Hannover, Germany and as used by Boliden-Bergsoe AB at Landskrona, Sweden. The batteries are drained and charged with fluxes (lime, silica and shredded scrap iron), coke and an amount of recycle lump slag. The slag has a melting point above 1000°C and maintains an open structure in the shaft until it nears the tuyere zone with a temperature of around 1150°C. [Pg.178]

Environmental Uses. Next to steel fluxing, environmental uses of lime are the biggest market, accounting for 24% of total lime consumption. These uses include air pollution control, water, sewage, and industrial wastewater treatment, hazardous waste treatment, etc. [Pg.178]

Tin slags account for a sizeable fraction of the world s tantalum production. These slags are melted in electric arc furnaces, together with coke and lime (as flux), and this pyrometallurgical process leads to the production of synthetic niobium/tantalum concentrates. The waste products of this operation are mechanically separated slags which can be used, for instance, as landfill. The exhaust gases from this process are of minor consequence if dust is eliminated by the use of filters. [Pg.781]
