ABSTRACT
In the given work results of researches on receiving agglomerate from phosphogypsum in the presence of a waste of extraction of brown coals are presented. For definition of optimum parametres of phosphogypsum agglomeration it was conducted by a method of planning of experiments with use of rototable plans of the second order. Using the received equations surfaces of responses and their horizontal sections have been constructed. Results of influence of Shubarkolsky coal
and a waste of extraction of Lengersky on the containing of sulphur and statistical durability agglomerated of phosphogypsum are resulted.
