— Properties of phosphogypsum for application in cements. The use of PG in cement production depends on the nature of the phosphate ore, the type of process employed, the efficiency of plant operation, the method of disposal, and the location and depth of the landfill or pile where it is discharged (Arman and Seals, 1990).
The phosphogypsum (PG) pile of solid waste is of immense proportions and poses a grave threat to the ecological environment, with its reserves steadily increasing year after year. The urgent need for large-scale consumption and high-quality utilization of PG in industrial production has become apparent. The present study provides a comprehensive analysis …

— Phosphogypsum (PG) is a by-product of phosphoric acid production and according to the Waste Management Strategy of the Republic of Croatia for 2007 – 2015 (Official Gazette 85/07, 126/10, 31/11, 46/15) it is classified under the waste code 06 09 01. Phosphogypsum has a significant impact on the environment by its effects, admixtures …
— Introduction. Phosphogypsum (PG) is a solid grey, moist, fine-grained by-product powder generated during the production of phosphoric acid which has the …
— In participation with the local farming community, we carried out a 4-year field experiment in Southern Kazakhstan to evaluate the effects of soil application of phosphogypsum—0, 4·5, and 8·0 metric ton per hectare (t ha −1)—on chemical changes in a soil containing excess levels of Mg 2+, and on cotton yield and economics.
— Based on the comprehensive effects of phosphogypsum on properties of cement, the phosphogypsum was used to develop an anti-cracking agent with citric acid as an auxiliary set retarder. This anti-cracking agent was added into the cement-stabilized base materials to apply the Continuous Construction Method (CCM).
— To restore degraded sod-podzolic soils, a peat-sand substrate enriched with compost from quail manure without and with the application of phosphogypsum to stabilize organic compounds of compost ...
— By incorporating phosphogypsum into the mix, the early strength development of lightweight soil is effectively improved. Moreover, with suitable mix …
difficult to distinguish phosphogypsum effect from the plant growth eect on soil Al chemistry. Therefore, further inves-tigations are necessary to elucidate the mechanisms and to understand the phosphogypsum rate eect. In this context, we aimed to examine the eect of phos-phogypsum application on the distribution of aluminum
— This review summarizes the state-of-the-art research on phosphogypsum application in agriculture and soilization, as well as ideas and suggestions for its …
Abundant of research investigations have been conducted to utilized the waste or chemical gypsum, phosphogypsum for various applications. Most of the research investigations were carried out by purifying phosphogypsum for the impurities present in it and then its utilization were suggested. In another research approach phosphogypsum could be utilized …
— As phosphogypsum constitutes a large amount of solid waste material, its purification treatment and comprehensive utilization have close connection with economic development and ecological environmental protection. For the moment, the storage quantity of phosphogypsum is still rising as a result of the increasing phosphate fertilizer …
— This study reports the application of phosphogypsum with cement and fly ash as a stabilization agent on two selected soils. In the light of the test results the following conclusions can be made: 1. Treatment with phosphogypsum, fly ash and cement generally reduces the plasticity index. Principally, a reduction in plasticity is an indicator of ...
— The environmental pollution caused by the discharge of phosphogypsum (PG) and phosphorous slag (PS) is a common issue for all countries. In order to fully utilize …
— Phosphogypsum (PG), a by-product of the phosphate industry, was incorporated with soil to determine effects of land disposal on crop growth and uptake of cadmium (Cd) and radium (Ra). Application …
— Phosphogypsum application generally improved soil physical properties, principally for soils of Chichaoua and Ras El Ain regions. Phosphogypsum, a coproduct from the processing of phosphate rock, represents a promising solution for improving soil quality. The improvement of the soil's physical attributes enhances the root, vegetative …
— The phosphogypsum valorization became a necessity when the U.S. Environmental Protection Agency (EPA) legislation was modified in 1992 and allowed the use of PG with an average 226 Ra of less than 370 Bq/kg for agricultural applications such as a soil amendment. Other areas in the world, however, looked at PG as a valuable raw …
— Phosphogypsum (PG) is one of solid wastes with large amount of yield and serious pollution, which has attracted wide attention. The aim of this study is to investigate filling performance of PG on polypropylene (PP) or high-density polyethylene (HDPE) matrix. In this work, PG was calcined initially to improve whiteness and fix impurities. X …
— The management of solid mine waste requires a detailed characterization and a full understanding of the reparation of elements in the origin rock and their distribution in the waste matrix (Elghali et al., 2018).It is now generally acknowledged that the distribution, mobility, availability, and toxicity of chemical elements are determined not …
— This study has been carried out to valorize the Moroccan phosphogypsum (PG) generated during the production of phosphoric acid. The enormous Mondial waste of PG is estimated to be more than 100 Mt/year, which has sparked interest in its usage in other sectors.
