Obtaining environmentalli safe mixed fertilizers containing trace elements based on carbonate-siliceous dolomitized phosphate raw materials and wastes CHP

Abstract

The article provides information about the environmental impact of man-made waste generated in industrial regions. Mineralogical and chemical properties of technogenic wastes of industrial regions, in particular, waste of coal mining, mining and industrial complex of phosphate and siliceous raw materials extraction in the Karatau phosphorite basin of the Republic of Kazakhstan are presented. The data on the chemical and mineralogical composition of ash and slag waste generated by the combustion of coal from the Karaganda and Ekibastuz basins are presented. The results of differential thermal and X-ray analyses of carbonate – siliceous dolomitized phosphate raw materials of the Aksai Deposit and its chemical composition are shown. The results of analyses of brown and hard coal ash from the Ekibastuz and Karaganda basins are presented. In addition, the reflectivity of ash formed after burning coal from the Bogatyr section of the Ekibastuz basin, as well as its physical and chemical properties and characteristics for macro and microelements, is given.
