Phosphogypsum is the most significant industrial solid waste in the world. Phosphogypsum has a complex composition and its traditional storage methods occupy large areas of land and also damage the environment. Currently, phosphogypsum is mainly used for the direct preparation of construction materials and chemical auxiliary …
Phosphogypsum (PG), the main industrial by-product of phosphate fertilizer industry, primarily consists of calcium sulfate dihydrate. However, it contains various impurities with variable quantities depending on the origin of the phosphate rock. These impurities can restrict the reuse of phosphogypsum as a secondary primary resource.
1. Introduction. Phosphogypsum (PG) is among the by-products emitted by the phosphorus chemistry industry. About 5 tons of PG are emitted for each ton of phosphoric acid produced [1, 2], and its reaction is shown in Eq (1).About 300 million tons of PG are added annually, and total stockpiles exceed 600 million tons [3].PG is complex …
The phosphogypsum is a by-product of the phosphate fertilizer industry. It has accumulated over several decades, and not only takes up a large amount of land, but also poses a significant risk to the environment and resource waste. In order to promote the use of phosphogypsum, its hydration hardening characteristics are studied using a …
Sandy soil covers a significant portion of Egypt's total land area, representing a crucial agricultural resource for future food security and economic growth. This research adopts the hypothesis of maximizing the utilization of secondary products for soil improvement to reduce ecosystem pollution. The study focuses on assessing the …
The P 2 O 5 and F are found in three forms: (i) on the surface of phosphogypsum crystals with water-soluble compounds (H 3 PO 4, Ca(H 2 PO 4) 2 ·H 2 O, NaF); (ii) substituted in the lattice of phosphogypsum crystal (effectively solid solutions of CaHPO4·2H 2 O or Na 2 SiF 6) in PG; and (iii) as insoluble compounds (Ca 3 (PO 4) …
Phosphogypsum (PG), a byproduct during the phosphoric acid production process, also known as the wet process, contains complex and diverse impurities, resulting in low utilization and considerable accumulation. This leads to a massive waste of land resources and a series of environmental pollution problems. Given the current urgent …
