The studies of many scientists on the use of various man-made wastes have established the possibility of their use in the ceramic industry. The mutual influence of industry and the environment acts as a component element of the ecological system “man - nature”. The increase in mining, the development of metallurgical production and thermal power engineering has led to a significant accumulation of various types of waste that are generated both in the process of mining and beneficiation of minerals, and at various stages of their processing. The Kaitash tungsten-molybdenum plant produces molybdenum and a large amount of solid waste is generated during the flotation process. The aim of the study is to study the chemical and mineralogical composition of this waste and to explore the possibility of using it in the ceramic industry, in particular for the production of ceramic masses and glazes

When learning a second language listening is considered to be a significant language skill to develop both in class and in self-study process. Learners consider listening as the most difficult language skill to learn and essential. Since the role of listening comprehension in language teaching has been repeatedly emphasized, many teachers do not pay enough attention to its importance in their classes. To give the stress on the teaching techniques and methods to develop listening skills a definition of listening and listening comprehension, a brief discussion of reasons for listening, followed by reviewing listening comprehension process, the importance of listening, teachers’ roles in listening comprehension, and discuss strategies, techniques, and goals of listening are described in this article

Selective catalytic reduction (SCR) denigration may increase the emission of NH4+ and NH3. The removal and transformation characteristics of ammonium sulfate aerosols and ammonia slip during the wet flue gas desulfurization (WFGD) process, as well as the effect of desulfurization parameters, were investigated in an experimental system equipped with a simulated SCR flue gas generation system and a limestone-based WFGD system. The results indicate that the ammonium sulfate aerosols and ammonia slip in the flue gas from SCR can be partly removed by slurry scrubbing, while the entrainment and evaporation of desulfurization slurry with accumulated NH4+ will generate new ammonium-containing particles and gaseous ammonia. The ammonium-containing particles formed by desulfurization are not only derived from the entrainment of slurry droplets, but also from the re-condensation of gaseous ammonia generated by slurry evaporation. Therefore, even if the concentration of NH4+ in the desulfurization slurry is quite low, a high level of NH4+ was still contained in the fine particles at the outlet of the scrubber. When the accumulated NH4+ in the desulfurization slurry was high enough, the WFGD system promoted the conversion of NH3 to NH4+ and increased the additional emission of primary NH4+ aerosols. With the decline of the liquid/gas ratio and flue gas temperature, the removal efficiency of ammonia sulfate aerosols increased, and the NH4+ emitted from entrainment and evaporation of the desulfurization slurry decreased. In addition, the volatile ammonia concentration after the WFGD system was reduced with the decrease of the NH4+ concentration and pH values of the slurry.
