Up to now it has not been finally decided which view mentioned above is correct regarding the reaction which takes place during the chlorination of lime. Industrially, bleaching powder is usually considered to bo a compound CaCl (0C1), without, however, attributing to this formula other than a merely qualitative meaning.

The BOS process replaced the Bessemer and open hearth steelmaking processes during the 1960 s and caused some major changes in both the steel and lime industries [27.1, 27.2]. The process is currently used for 70% of the world s steel production, with most of the remainder being in electric arc furnaces (EAF). The main processes in iron and steelmaking are illustrated in Fig. 27.1. 

The requirements of the BOS process have set the quality standards for much of the lime industry in many countries since the 1960s. They have influeneed the selection of limestone, kilns, fuels, operating parameters and the design of lime handling plants (see chapters 14, and 16 and section 17.1).

The lime industry generally has a lower accident rate than quarrying. Contributory factors are likely to be the reduced use of mobile equipment and the greater size of the works — there is a correlation between accident rate and the number of people employed on site [34.8]. Tripping and falling constitute the largest category of accidents.

I also owe a great debt of gratitude to my former colleagues and friends at Buxton Lime Industries Ltd. (until 1990, the lime business of ICI pic) for their help and advice throughout. They are too numerous to mention by name, but have personally received my heartfelt thanks. I could not have written this book without their support. 

In this project, two sources of lime - commercial hydrated lime and Maerz kiln dust (MKD) lime - supplied by Buxton Lime Industries were used as a source of alkali in the paste mixtures. 

Suggestions for tendering, ordering and guarantee agreements are given in Appendix D of VDI 2570 "Noise abatement in factories". Further information on these matters is contained in the Technical Information Note "Noise abatement in the works of the lime industry" (Technisches Merkblatt, Bundesverband der Deutschen Kalkindustrie, 1975) and the Code SEB 905003-63 (1963). 

In the cement industry, particle size classification by screening as part of the production operations is of less importance than, say, in the lime industry or in coal and ore preparation. Indeed, true classification procedures in the primary size reduction stage do not occur in cement manufacture, since the aim of the crushing treatment is to produce a feed material suitable for grinding to a fine powder, not the production of size fractions as required for crushed stone used in road construction, concrete production, etc. 

Bauxite is used for refractory materials production which is used mainly in the steel industry for transport ladles and electric arc furnace roofs, and in the cement and lime industry for rotary kiln linings. Besides, there are three aluminium polymorphs used in refractory industry, namely sUlimanite, andalusite and kyanite, which share the same simple chemical formula (A SiOs). Those minerals differ in their crystallographic structures and stabilities with respect to both pressure and temperature and sillimanite is most desirable as a refractory raw material, as it fires with little or no change in volume and requires no pre-firing. LIBS is very helpful in...

Test samples. Dolomite produced in Kuzuu, Tochigi Pref., was used. It was burnt at 973-1073 K for 4 h. Burnt materials were ground with a mill to obtain the mean particle diameter of 18 pm. To obtain comparison data, using MgO, CaCOs, Mg(OH)2 (by Kanto Kagaku Inc.), slaked lime (by Yoshizawa Lime Industry Co., Ltd.,).
