The
slowing down of bioactive elements (Cu, Co, Mo) leaching from the Granulated
phosphogypsum
Abstract
It was studied experimentally the leaching of
bioactive elements (Cu, Co, Mo) from carbamide-free and high-carbamide
compositions based on phosphogypsum. These compositions are usable as complex
fertilizers. It was demonstrated that the Mo-, Cu- and Co- salts leaching from
carbamide-free phosphogypsum granuls are more than from granuls with high
carbamide content. The effect is determined by the distinction between the
porosity and water-resistance of carbamide-free granuls and granuls with
carbamide.
