· Early studies carried out by Bridgman suggested the only possible synthetic route to BP was under controlled temperatures and high pressures [13, 24]. However, moderately low pressure and temperature conditions with red phosphorus powder in the presence of a mineralizing agent have produced bulk BP [ 25 – 27 ].

· It can be seen from the presentation above that (i) the concentrations of nitrogen and phosphorus in Sihe and Shendinghe Rivers are higher than those in other tributaries; (ii) TP, TN and DIN are in the forms of DTP, DTN and N O 3 −-N, respectively, in May, August and December; (iii) compared with nitrogen, phosphorus is more likely to be the limiting factor of …
The effect of CaCO3, Na2CO3, and CaF2 on the reduction roasting and magnetic separation of high-phosphorus iron ore containing phosphorus in the form of Fe3PO7 and apatite was investigated. The results revealed that Na2CO3 had the most significant effect on iron recovery and dephosphorization, followed by CaCO3, the effect of CaF2 was negligible.
· When producers pay special attention to managing phosphorus (P), it can lead to profitable crop production. The best way to use fertilizers to meet P requirements changes with crop, soil properties and environmental conditions. Finding the best P source Inorganic commercial P fertilizers have evolved over the last several decades into a refined, predictable …
Study on the mechanism of dephosphorization in roasting process for direct reduction of high-phosphorus oolitic hematite in West Hubei [J]. Journal of University of Science and Technology Beijing, 2022, 32(8): 968974.
· Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (, due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside improvements …

· This study focused on the characterization of the self-formed slag when melting DRI produced by hydrogen reduction. The partitions of phosphorus and vanadium between slag and metal were related to the degree of reduction in the range of –%. The phases formed in the slag after melting were characterized.
International Journal of Minerals, Metallurgy and Materials (IJMMM, ISSN 1674-4799, CN 11-5787/TF, monthly, started in 1994, formerly known as Journal of University of Science and Technology Beijing) is an international journal devoted to publishing original research articles (and occasional invited reviews) on all aspects of minerals processing, physical metallurgy, …
This study investigates the level of wastewater pollution by analyzing its chemical characteristics at five wastewater collectors. Samples are collected before they discharge into the Danube during a monitoring campaign of two weeks. Organic and inorganic compounds, heavy metals, and biogenic compounds have been analyzed using potentiometric and spectrophotometric methods.
Potatoes have high nutrient demands, as they require approximately 220 lb nitrogen (N), 30 lb phosphorus (P) and 300 lb potassium (K) per acre to produce a 450 cwt./acre yield of Russet Burbanks, a typical yield for southern Idaho.

Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43-), located in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Animals absorb phosphates by eating plants or plant-eating animals.
and dephosphorization processes such as Moving Bed Biofilm Reactor, Anaerobic ammonia (nitrogen) oxidation, Aerobic granular sludge + membrane technology are all developed on the basis of breaking the traditional biological nitrogen and phosphorus removal principle. New Technology of the Original Technology Improvement and Combination
· Moreover, the SND process had been applied for the removal of phosphorus pollutants from municipal wastewater, showing the SND process is feasible in phosphorus removal (Salehi et al., 2022).
