Hazardous solid waste from metallurgical industries.
Types of land disposed residuals from selected metal smelting and refining industries are described, as are the origin and disposition of land disposed residuals from the primary copper industry as an example. Quantities of land-disposed or stored residuals, including slags, sludges, and dusts, are given per unit of metal production for most primary and secondary metal smelting and refining ind...
متن کاملLead Speciation in the Dusts Emitted from Non-Ferrous Metallurgy Processes
The paper presents results for the speciation analysis of lead in dusts derived from dedusting of technological gasses from metallurgical processes of non-ferrous metals with different elementary content, made in accordance with two equal sequential extractions. Analytical procedure A provided possibilities for determination of fraction of Pb(2+), metallic lead and fraction containing mainly le...
متن کاملA study of the thermal environment in non-ferrous foundries.
Foundries where non-ferrous metals are cast are often very hot and it is not uncommon in the height of summer for a foundry to be closed shortly after midday because conditions become too hot for sustained work. This survey of typical working environments in such foundries was made at the request of a Joint Standing Committee of the Ministry of Labour and National Service consisting of represen...
متن کاملRF Thermal Plasma Synthesis of Ferrite Nanopowders from Metallurgical Wastes
RF thermal plasma synthesis of zinc-ferrite nanopowders has been studied from metallurgical wastes of high iron oxide and zinc oxide and/or hydroxide content. XRD measurements of the products revealed that an extensive spinel formation took place on RF plasma treatment. However, instead of expectable ZnFe2O4, formation of zinc ferrous ferrites (Zn0,7Fe2,3O4 and Zn0,4Fe2,6O4) was concluded from ...
متن کاملVegetable ingredients of dusts in textile and nontextile cotton industries.
The objective was to determine if garnetting and raw cotton dusts differed in botanical composition. Estimates of dust composition were based on the contents of gross trash in cotton raw materials and the potential of each gross trash component to be converted into less than 10 mum particulate by a laboratory abrasion test. All types of garnetting dusts are predicted to contain a lower percent ...
