Abstract
The work of the factory for the production of fertilizers in the area of Veles (Republic of North
Macedonia) resulted in a residual amount of approximately 3.4 million tons of phosphogypsum, which was deposited
at the dump adjacent to the plant between 1980 and 2003. So far, no remediation of the phosphogypsum dump has been
performed. This paper presents the results obtained from representative samples taken from the phosphogypsum dump
by applying the following methods: analytical methods (ICP-MS, FUS-ICP-MS), mineralogical methods, X-ray powder
diffraction (powder-XRD), electron microscopy (SEM-EDS), and high-resolution γ-ray spectrometry. The samples
contain crystalline gypsum (Ca-sulphate), Fe-hydroxide, Ba-sulphate, Ca-fluoride, Si-oxy-hydroxide and zircon.The
gross alpha specific activities varied between 820 Bq/kg and 1090 Bq/kg with an average of 950 ± 104 Bq/kg, while
the gross beta specific activities ranged from 1380 Bq/kg to 1980 Bq/kg with an average of 1694 ± 220 Bq/kg.
