The phosphate production generates also mining wastes, which contain many recoverable elements, including rare earth elements (REEs) (Alonso et al., 2012; Kechiched et al., 2018). REEs contain a total of 17 elements, 15 lanthanides belonging to the block f ( 57 La, 58 Ce, 59 Pr, 60 Nd, 62 Sm, 63 Eu, 64 Gd, 65 Tb, 66 Dy, 67 Ho, 68 Er, 69 Tm, 70 Yb, and 71 Lu).
1/2/2015#0183;#32;Potential annual REE production from operating phosphate mines is calculated using our mean phosphate REE concentration (Supplementary Data 1) and the annual phosphate produced from Miocene phosphate (Florida + Carolina = Mt) and Phosphoria Formation ( Mt) (Jasinski, 2011). Estimated REE content of the Love Hollow Formation, Arkansas, inferred from its areal distribution, thickness,
In 2015, global demand for rareearth elements was 149,000 metric tons per year, according to Mary Anne Alvin, technology manager of rareearth elements at the Department of Energys National

Final. Abstract. The extraction and recovery of rare earth elements from phosphate rock, phosphoric acid, and three phosphate fertilizer waste byproducts, phosphogypsum, amine tailings, and waste clay, using a novel aqueousbased extraction solution and an adsorption polymer, poly 1octadecene 2,5furandione salt, are examined.

2 #0183;#32;The amount of total rare earth elements varies from deposit to deposit, but each deposit is enriched in the heavy rare earth elements, which are far less common than the light rare earth elements. Total rare earth elements range from zero to nearly % for the waste and tailings piles and zero to nearly % for ore.
To meet the growing global demand for rare earth elements (REEs), nontraditional mining sources of these metals are being investigated. Phosphate ore and phosphate mining wastes have been identified as possible alternative sources to REEs. In this study, REEs were extracted from Florida phosphate mining materials using mineral and organic acids.
In addition to the occurrence of the rareearth elements in nature in a variety of rare earth mines, a considerable proportion of REE come from the symbiosis with apatite and phosphate rock ores. The total reserves of phosphorite ore in the world are about 100 billion tonnes, while their average content of
Potential dangers of mining rare earth metals
Monazite ((Ce,La,Y,Th)PO 4) A rare earth phosphate containing 5078% REO. It is recovered as a component of heavy mineral sands and is a major source of thorium which imparts radioactive properties to the mineral. Xenotime (YPO 4) A yttrium phosphate containing
These results suggest that this process may be an efficient means of recovering rare earth elements and phosphorus from phosphate mining waste products. The rare earth elements (REE) or rare earth metals are vital components in many modern electronics and are critical to the advances in several high technology fields, including green energy.
Jul 30, 2019#0183;#32;The filter captured 4060% of the rare earth elements and radioactive elements in a fiveminute single passthrough from wetprocess phosphoric acid and 80% of the rare earth elements
As reported in, the filter captured 4060% of the rare earth elements and radioactive elements in a fiveminute single passthrough from wetprocess phosphoric acid and 80% of the rare earth elements in a fiveminute single passthrough from sulfuric acid leached waste.
Monazite is a reddishbrown phosphate mineral that contains rareearth to variability in composition, monazite is considered a group of minerals. The most common species of the group is monazite(Ce), that is, the ceriumdominant member of the group. It occurs usually in small isolated has a hardness of to on the Mohs scale of mineral hardness and is relatively
Demand for elements varies by element group (see Table 1) and the variety of strategic elements results in a similar variety of supply problems. For some elements, such as the rare earth elements (REEs), the problem is production.
The extraction and recovery of rare earth elements from phosphate rock, phosphoric acid, and three phosphate fertilizer waste byproducts, phosphogypsum, amine tailings, and waste clay, using a novel aqueousbased extraction solution and an adsorption polymer, poly 1
Mar 27, 2019#0183;#32;But large amounts of rareearth elements exist in phosphogypsum (PG), a waste product from producing phosphoric acid from phosphate rock. The mined approximately 28 million tons of phosphate
May 26, 2020 by Canadian Mining Journal . QUEBEC Focus Graphite has sold its 50% stake in the Kwyjibo rare earth element deposit to Investissement Qu#233;bec, a financing corporation that exists to facilitate investment in Quebec, for million.
5/4/2019#0183;#32;Rare earth metals are used in wind turbines, also, which means that even though clean energy is generated, the use of these toxic metals makes the green energy impure. Rare earth metals mining generate a lot of radioactive waste which is dangerous for both humans and the environment. Take a look at the potential dangers of mining rare earth metals:
In an era of environmental degradation, and water, and mineral scarcity, enhancing microbial function in sustainable mining has become a prerequisite for the future of the green economy. In recent years, the extensive use of rare earth elements (REEs) in green and smart technologies has led to an in
