LKAB produces Apatite from mine waste in new pilot plant

Here, the apatite will be processed into phosphorus mineral fertilisers, rare earth elements, fluorine and gypsum. The EU lists both Phosphorus and REEs as Critical Raw Materials. This is due to their high economic importance and our import dependence. But right now, Leif Boström is pleased to be able to inform of the successes with the apatite production that is the needed first step.

Plant-driven weathering of apatite--the role of an

The mycorrhizal trees were grown in specially designed sterile microcosms in which the supply of soluble phosphorus (P) in the bulk media was varied and grains of the calcium phosphate mineral apatite mixed with quartz, or quartz alone, were provided in plastic wells that were only accessed by their fungal partner. Under P limitation, pulse labelling of plants with (14)CO(2) revealed plant-to-fungus allocation of photosynthates, with 17 times more (14)C transferred into the apatite

mechanisms to increase phosphorus availability and facilitate uptake (Raghothama, 1999). Many soil fungi are able to solubilize phosphorus directly from minerals such as apatite (Ca 10 (PO 4) 6 (OH,F,Cl) 2). Both plant-symbiotic and free-living soil fungi have been demonstrated to increase phosphorus uptake in plants through their biogeochemical activity

Phosphorous availability influences the dissolution of

known to increase plant-available phosphorus by promoting dissolution of various phosphate minerals. Yet no apatite dissolution studies exist using fungi as weathering agents, and regulation of fungal weathering activity in response to different levels of phosphorus availability is largely unknown. Fungi were isolated from a grassland soil in northern California. Three pathways of tri-calcium

Apatite: From Crystals to Phosphate Rock Rock & Gem

In the form of apatite, phosphorus is essential to plant life for growth and photosynthesis, and to animal life as a vital component of genes, teeth, bones, and muscles. Fluorapatite, the hardest, most durable and abundant, of the three apatite minerals, is the primary component of vertebrate bones and teeth. When fluoride compounds are added to drinking water and toothpaste, fluorine ions

Phosphorus removal from wastewater by mineral

01/08/2006 Phosphorus affinity was found to be higher with Cargill sedimentary apatite as substrate, compared to igneous apatites in batch experiments. Sedimentary apatites are believed to favour crystallization of HAP due to intrinsic characteristics, notably their internal porosity. The presence of secondary minerals associated to the gangue would be beneficial by contributing to a source of Ca,

Synthetic apatite nanoparticles as a phosphorus fertilizer

14/07/2014 Some soluble phosphate salts, heavily used in agriculture as highly effective phosphorus (P) fertilizers, cause surface water eutrophication, while solid phosphates are less effective in supplying

Phosphorus Fertilizer: The Original and Commercial

12/03/2018 Earlier the original source of phosphorus (P) fertilizer was bones; as time passes, the supply of P fertilizer will get exhausted. Today, rock phosphate is the only raw material in the form of P fertilizers. There are two types of rock phosphates: igneous and sedimentary; both have the same phosphate mineral, i.e., calcium phosphate of apatite group. The general formula for pure rock

Mycorrhizal fungi control phosphorus value in trade

Apatite is difficult for plant roots to dissolve directly, however arbuscular mycorrhizal fungi can help break down apatite (Reynolds et al., 2006; Pel et al., 2018). Past work has shown that arbuscular mycorrhizal fungi can increase the dissolution and uptake of apatite, even under sterile conditions when no other microbes are present (Reynolds et al ., 2006 ; Pel et al ., 2018 ; van’t

Phosphorus Gilmour - Major Reference Works Wiley

26/03/2019 The majority of phosphorus plants in China and Vietnam are smaller (15–30,000 kW) and simpler than those built in the West in the late 1960s. Estimates of installed capacity in China are imprecise but could be as high as 2–2.5 m tonnes, about three times the domestic demand. The capacity decline in the West has been a result of the growth of wet process phosphoric acid supplying all

Fighting big farm pollution with a tiny plant Science

This plant needs nitrogen and phosphorus, just as the algae do. Julia reasoned that duckweed might soak up some of the phosphorus from fertilizer runoff before it reached the algae. To test this, she filled nine glass containers with water and then added phosphorus. To figure out just how much phosphorus to add, Julia used a test kit from her local pet store. Adding the kit’s chemicals to a
