  Preparation of belite–sulphoaluminate cement using phosphate rock …

  2022314 · Abstract In the phosphorous–sulfur two-step process involved in the clean production of phosphoric acid, the acidolysis of phosphate rock yields a solid filter phosphate rock acid-insoluble residue (PAIR). Herein, belite–sulfoaluminate cement is prepared using the PAIR as the main silica source to promote the residue resource utilization.

  Sustainable use of phosphorus: A finite resource

  201391 · Phosphorus is essential nutrient and a pillar of food security, but phosphate rock is a finite, non-renewable resource. Due to its highly dissipative nature, recycling and closing phosphate loops are essential in order to reduce its impacts on aquatic systems and biodiversity ( Carpenter and Bennett, 2011, Venterink, 2011 ).

  Changes on phosphorus fractions and paddy yield using …

  2024122 · Abstract Agricultural soils are usually deficient in phosphorus (P), causing yield reduction. To boost crop production and P availability in acid soil, rock phosphate (RP) can be used with single super phosphate (SSP), which can also supply available P for the long-term during a crop cycle. The study was conducted to show the effect of SSP and …
