Horwit et al. discovered that there was a simple correlation between the molar concentration of water in the organic phase and the extraction of strontium nitrate from nitric acid solutions by cis-dicyclohexano-18-crown-6 [7]. Numerous extraction systems have reached similar results about the role of water molecules during ionic extraction [8 ...
In Morocco, phosphate stands out as a strategic resource (Fikrat et al., 2023): in 2020, 23% of extracted and washed phosphate rock, 27% of produced phosphoric acid and, a significant 96% of the manufactured fertilizer were exported (OCP, 2020). This means that the Moroccan economy benefits significantly from this resource.

This plant ...
2.2. Extraction, scrubbing, and precipitation experiments. TBP supplied by Merck was used as the extracting agent. As an organophosphorus ester, TBP can extract rare earth ions (RE 3+) from nitrate media according to the following reaction: (3) R E (aq) 3 + + 3 N O 3 (aq)-+ 3 TB P (org) → RE (N O 3) 3 · 3 TB P (org) Kerosene was used as …
The rich phosphate deposit comprises approximately 2–6 layers (0.5–1.5 m thickness), mixed with other (low-level) phosphate layers that are not relevant for mining. The phosphate deposit rock is from the same geological period and is part of the Mediterranean phosphate belt that extends from Turkey through Jordan to Israel.
Acid phosphate extractants are synthesized via esterification with phosphorylation reagents and hydroxyl compounds as raw materials, and the phosphate products mainly include mono phosphoric acids, dialkyl phosphoric acids, and pyrophosphate (Peppard et al., 1959).In this study, PTOPP was synthesized through …
