Phosphorus Release by Low Molecular Weight Organic Acids from Low-Grade

Low molecular weight organic acids (LMWOAs) are naturally occurred in soil, particularly in the rhizosphere due to microbial metabolites and secretion of root exudates. Various functional groups present in LMWOAs can play an effective role in phosphorus dissolution. In this study, potentiality of LMWOAs for phosphorous release from low …

Phosphorus (P) fertilizers are produced from high-grade rock phosphates (HGRPs). The reserve of HGRP is finite and non-renewable. We are rapidly shrinking this reserve, by producing P fertilizers. This fact establishes the need of utilizing low-grade rock phosphates (LGRPs) for growing crops. In this experiment, LGRP was treated with 0.5 M …

Phosphorus recovery from high concentrations of low-grade phosphate

Sulfuric acid is used widely for acidulation due to its low cost when compared with phosphoric acid. However, sulfuric acid turns out to be the main energy requirement in the wet process of phosphate rock (Dawson and Hilton, 2011), which makes it suitable to acidulate only high-grade phosphate rocks, i.e. low contents of carbonates and impurities.
