Spatial Modeling of Phosphogypsum Dusting of Disposal Site Using the Example of the Balakovo Branch of Apatit JSC [ПРОСТРАНСТВЕННОЕ МОДЕЛИРОВАНИЕ ПЫЛЕНИЯОТВАЛАФОСФОГИПСА НА ПРИМЕРЕ БАЛАКОВСКОГОФИЛИАЛА АО"АПАТИТ"]

The simulation of dusting of phosphogypsum dump of Balakovsky branch of JSC "Apatit" of "PhosAgro" Group of Companies was conducted. On the basis of the analysis of the meteorological data for the period 2006-2019, the information on a projective covering by vegetation for the period 2006-2019, a relief and a soil map modeling of relative concentration for the particles the size less than 0,01 mm; 0,01-0,03 mm; 0,03-0,05 mm; 0,05-0,1 mm; 0,1-1 mm and 1-8 mm was done. It was found as a result of the joint analysis of the constructed maps and field data, that the map of the weighted sum of relative concentrations of the analyzed particles well enough reflects spatial variability of the maintenance in soil La and Ce, prevailing components among the analyzed rare-earth elements (correlation coefficient 0.74 and 0.68 accordingly). The modeling results can be used to assess the impact of phosphogypsum dumps on the adjacent territory and its soil cover. © 2022 Izdatel'stvo Kalvis. All rights reserved.
