In the following sections, the most important commercial applications of solvent-extraction technology in the field of extractive metallurgy are discussed in terms of the coordination chemistry relevant to the extraction process. The sole criterion for the inclusion of a given process is that it should have been utilized on an industrial scale. It may be noted that several interesting extraction systems in the early stages of development have been excluded on this basis, despite the pertinence of the chemical principles involved. [Pg.789]

Several industrial catalytic reactor with periodical flow reversal arc used in nonferrous metallurgy for treatment of lean sulfurous gases with SO2 concentrations varying from 1% to 4.5% [9, 27]. The inlet temperature of such an exhaust gas is typically 40-60 °C, while the minimum reaction temperature is 370-400 °C. Utilization of these gases by traditional methods... [Pg.500]

At the University of Chemical Technology and Metallurgy (UCTM), the Faculty of Ecology and environmental protection, among the issues for education and research are - the industrial waste utilization and natural resources and their protection monitoring. There is a close co-operation between the UCTM s Scientific Research Centre and all Bulgarian scientific... [Pg.304]

Precipitation is a widely used industrial process. It is also a very popular laboratory technique, especially in analytical chemistry, and the literature on this aspect of the subject is voluminous (see Kolthoff et al, 1969). Precipitation plays an important role not only in chemistry but also in metallurgy, geology, physiology, and other sciences. In the industrial field, the manufacture of photographic chemicals, pharmaceuticals, paints and pigments, polymers and plastics utilizes the principles of precipitation. For the production of ultrafine powders precipitation may be considered a useful alternative to conventional crystallization followed by milling. [Pg.315]

In particular, their papers presented at the 1988 TMS Extractive Metallurgy of Nickel and Cobalt Conference complement each other, with leach solutions described in one paper [10] treated to precipitate iron as jarosite as discussed in the second [11]. They also make reference to the various techniques utilized for iron precipitation in the zinc industry and options considered for their own studies ... [Pg.77]
