Abstract
Phosphogypsum is a waste product in the production of phosphoric acid and can be considered as a raw material for the production of various types of mineral fertilizers. As a result of the conducted research, technical solutions for processing phosphogypsum with the production of granular mineral fertilizers are proposed: type P with a content of assimilable phosphorus of more than 49%; type PKS with a content of phosphorus of 28%, potassium of 28%, sulfur of 10%; type NPKS with a content of nitrogen of 15%, phosphorus of 15%, potassium of 15%, sulfur of 10%; type NS with a nitrogen content of 30%. The resulting fertilizers contain a set of trace elements and have a granule strength above 4 MPa
