Abstract
A safe and profitable method of utilizing phosphogypsum byproduct has been devised involving pretreatment of the sample to minimize impurity content, followed by reaction of the residual phosphogypsum with ammonium carbonate to produce ammonium sulphate fertilizer. The prepared fertilizer was subjected to some physico-chemical tests which proved it to be of good quality, suitable for modulating the pH of the highly alkaline Egyptian soil.
