The latest in a controversial shipment of phosphate rock from Western Sahara is set to arrive in Tauranga this weekend. The IVS Phoenix is scheduled to arrive at the Port of Tauranga on February 27.
Phosphate rocks are by far the most important phosphorus-bearing raw material used in the fertilizer industry. They are the primary source of phosphorus (P), which is an essential element for agriculture and various industrial applications (e.g., animal feed, cosmetics, and electronics) [1,2].Phosphate rocks are also likely to host significant amounts of rare earth elements (REE), making them ...

Chapter 4. Evaluation of phosphate rocks for direct application. Chapter 3 described the characterization of phosphate rock (PR) materials for direct application. Depending on their origin and geological history, PRs show great variability in their inherent properties, especially in their grade, beneficiation requirements and apatite reactivity.
Chemical properties. The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, H
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams).
The rock was determined to contain phosphate. Dr. Simmons launched the earliest attempt in Florida at mining and using phosphate in 1883. His attempts were short-lived, but by 1883 phosphate was also reported at other locations in Alachua, Clay, Duval, …
The company's Lac à Paul phosphate rock project in Quebec, Canada, is at BFS (bankable feasibility study)-stage; in fact it's been at BFS-stage since 2013. In the above chart, Arianne's -owned Lac à Paul is the largest and has the highest concentrate grade phosphate project not owned by a major.

A Short History. Phosphate is a natural, non-renewable resource that is obtained by mining phosphate-containing minerals. Florida's phosphate rock deposits are believed to have originated when conditions in the seawater caused dissolved phosphorus to solidify and form the sediment that is mined today (1).
Defluorinated and Fused Phosphate Rock. Defluorinated phosphates are obtained by calcining or fusing phosphate rock with silica and/or phosphoric acid in the presence of water vapor. At temperatures ranging from 1,400° to 1,600° C., the bulk of …
Partial acidulation of phosphate rock. Partially acidulated phosphate rocks (PAPRs) are prepared by reacting PRs, usually with H 2 SO 4 or H 3 PO 4, in amounts less than that needed to make SSP or triple supersphosphate (TSP), respectively. The use of PAPRs has been widespread in Europe and South America since Nordengren (1957) first reported ...
Nauru is the smallest country in the world, with an area of 21 km2 and population of roughly 13,000. Located in Micronesia, this small island state is heavily dependent on international aid due to its colonial history and excessive mining of phosphate.
Arianne Phosphate Is Looking Hot. October 26, 2021 (Investorideas.com Newswire) Arianne Phosphate has a very advanced stage, shovel-ready, phosphate rock project in mining-friendly Quebec with two ...
In the past, rock phosphate was used to supercharge inorganic fertilisers like superphosphate — this is what most of the Australian miners are aiming their production for. To use the 'organic' raw form, poses a few problems. Phosphorus, the element, is not easy for plants to extract from soil generally and they take up between 5-20 per cent.

Soft rock phosphate, also called CalPhos or colloidal phosphate, is a great source of potassium and calcium for your plants. Our CalPhos comes from phosphate rock mined in Florida, which was formed millions of years ago from the mineralized remains of marine creatures. Soft Rock Phosphate should not be confused with Hard Rock Phosphate.
Ahead of the publication of the 2017 Phosphate Rock Cost Report, CRU undertook a research visit to Egypt's largest mine, Abu Tartour, as the mine's operator, Misr Phosphate Co., plans to construct its first phosphoric acid plant at the site. Egyptian phosphate rock is low cost but also low value. Downstream facilities in Egypt remain modest ...

Phosphate rock describes an imprecise series of minerals, all belonging to or variations of the apatite group of minerals (Figure 1). As a whole the general chemistry is A 5 (XO 4 ) 3 (OH,F,Cl), where A is generally Ca and X is P, however the mineral group as a whole can accommodate over half the periodic table amongst the two sites.
