Abstract

Embodiments herein generally relate to a process for producing a solid phosphate fertilizer comprising micronized elemental sulfur. The process of producing a solid fertilizer comprises the steps of: (a) combining micronized sulfur with one or both of phosphate rock and phosphoric acid; (b) reacting the phosphate rock and phosphoric acid to produce TSP mixed with micronized sulfur particles; and (c) granulating the TSP and micronized sulfur into fertilizer granules.
