Ecological Systems and Devices Annotation << Back LARGE – SCALE WASTES OF THE CHEMICAL INDUSTRY: ANALYTICAL APPRECIATION AND SYSTEMATIZATION OF THE TECHNOLOGICAL DECISIONS L.Ya. Shubov, S.I. Ivankov, I.G. Doronkina, K.D. Skobelev, D.A. Zagorskaya The study presents the results of analytic research of the problem of the chemical industrial wastes. The chemical composition and behavior in technological processes of phosphogypsum and the product of pyrite roasting as a tethnogenic raw material are considered. The directions of used chemical industrial wastes is shown. It is noticed that storage of waste in the dumps of waste leads to environmental pollution. The technological aspects of waste treatment, extraction metals from waste and the advantages its use in construction (as a mineral concrete admixture) are considered. Keywords: waste; the product of pyrite roasting; phosphogypsum; technology. DOI: 10.25791/esip.03.2019.484 Contacts: E-mail: doronkinaig@mail.ru Pp. 08-30.
