The phosphate rock contains about 3–4% fluoride. F/P 2 O 5 weight ratios range from 0.10–0.14 and 0.04–0.06 for sedimentary and igneous rocks, respectively (Becker, 1983).The fluoride in the rock is converted into volatile compounds such as HF (from the reaction with sulphuric acid) and H 2 SiF 6 (from the further reaction of HF with …

Plants strive for phosphorus (P), which is an essential mineral for their life. Since P availability is limiting in most of the world's soils, plants have evolved with a complex network of genes and their regulatory mechanisms to cope with soil P deficiency. Among them, purple acid phosphatases (PAPs) are predominantly associated with P …

1.. IntroductionIronically, while the West-African region has enough phosphate rock (RP) deposits to be self-sufficient in the production of P fertilizers (Roy and McClellan, 1986), a large proportion of the soils in the region is deficient in P (Jones and Wild, 1975, Bationo et al., 1986).As even high-quality RP has a relatively low solubility …

1. Introduction. Phosphate rock (PR) is a nonrenewable nonmetallic mineral resource commonly employed as a chemical raw material (Wu et al., 2019).There are a considerable number of lean ore and few rich ore phosphate rocks in China, while low- and middle-grade rocks (P 2 O 5 <30%) account for approximately 90% of the reserves, with …
Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils.
