Quezon City 1101 Philippines The rare earth elements (REEs) are crucial components of green technology and are now considered critical raw materials. One of the emerging tools in mineral exploration, laser-induced breakdown spectroscopy (LIBS), was used by several studies to determine the REE contents of different geological materials.
Rare earth elements (REE) include the lanthanide series (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. All these metals occur together in different types of REE ...
This paper reviews the available information on the geology, mineralogy, and resources of the significant rare earth element (REE) deposits and occurrences in the …
REEs are found primarily in the earth's crust in three forms: (1) as the key constituent elements of minerals; contained in the crystal lattice of minerals in the form of ionic compounds and form ...
The majority of the phosphogypsum produced by a fertilizer plant in the Philippines is just stockpiled, which is considered a liability with no commercial prospects. It is important that we find use of this industrial waste by-product sooner than it becomes an environmental issue. ... Our study investigated the economic potential of the ...
In the Philippines, the REE potential of different mineral deposits was evaluated by examining the existing literature combined with new geochemical data.
In this study, we present mineralogical and geochemical characterization of samples systematically collected from a nickel laterite profile at the Sta. Cruz nickel laterite deposit, Zambales, Philippines. Wavelength-dispersive X-ray fluorescence spectroscopy (WDSXRF), mass-balance element mobility calculations, transmitted and reflected light …
Resource Geology journal publishes papers on economic geology, geochemistry, and environmental geology, with an emphasis on earth sciences of mineral deposits. Abstract Weathered crust of granitic rocks of two geochemically …
The unique properties of rare earth elements (REEs) (Fig. 2.1) make them useful in a wide variety of applications, such as alloys, batteries, catalysts, magnets, phosphors, and polishing compounds.The REEs and their primary uses by manufacturing sector are covered in Table 2.1.Four main geologic types of REE resources supply REEs and rare earth oxides …
The Philippines is leaving no stone unturned in its quest for rare earth elements, or REE—a major component of electronic products. The Mines and Geosciences Bureau (MGB) said the government had ...
Rare earth mineral deposits in Mongolia are carbonatite and alkaline rock related. Carbonatite deposits formed in continental rift zones in South Mongolia and have complex mineralization, e.g., REE-P-Sr-Ba-F-Pb and Fe- REE. Deposits associated with alkali granite and syenite also have Zr-Nb-REE mineralization and formed in an active continental ...
According to GlobalData, the Philippines is the world's second-largest producer of nickel in 2023, with output up by 1% on 2022. Over the five years to 2022, production from the Philippines increased by a CAGR of 1% and is expected to drop by a CAGR of 0.27% between 2023 and 2027.
Rare-earth element - Minerals, Ores, Uses: The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as …
Various rare earth mineral deposit points have been identified, such as North Nam Xe, Nam Nam Xe, Dong Pao (Lai Chau), Muong Hum (Lao Cai), and Yen Phu (Yen Bai). There are also some small rare earth deposits scattered along the coast from Quang Ninh to Vung Tau. The environmental and social impact of rare earth minerals extraction and processing
Does Philippines have rare earth minerals? The Philippines does produce a significant amount of phosphogypsum (PG), which can contain elevated concentrations of rare …
Rare earth elements (REE) include the lanthanide series (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. All these metals occur together in different types of REE deposits such as carbonatites, alkali syenites and monaziterich placers, and are found in more than 250 minerals in the Earth's crust. The future of the world's green …
The second-largest producer of rare earths from mines is the United States, which extracted some 43,000 metric tons of rare earth mineral concentrates in 2023, as well as 250 metric tons of rare ...

In the Philippines the wet-phosphoric acid process with sulfuric acid is used to produce mineral fertilizers from imported PR. In this process approximately 80% of the rare earths transfer from the PR raw material into the PG matrix, with the remainder transferring to the wet-phosphoric acid that is further used for mineral fertilizer production.
