Indonesia has many potential mineral resources including some rare earth elements (REE) minerals, such as monazite and xenotime.Their occurence is in association with tin ores (cassiterite).
Approximately >50% of global rare earth element (REE) resources are hosted by carbonatite related deposits, of which monazite is one of the most important REE minerals. Monazite dominates more than 30 carbonatite-related REE deposits around the world, including currently exploited mineralization at Bayan Obo and Mount Weld. These …
The resulting production facilities will extract 180 kt to 7.2 Mt rare-earth ore annually to generate 1.5 to 20 kt oxides of heavy and light groups of rare-earth metals along with the rare metals.
This REE ore deposit consists of poorly-liberated synchysite-(Ce), which hosts the light rare earth elements including Nd plus some heavy rare earths and well-liberated apatite, which hosts 50% of ...
These elements are typically split into two sub-groups, the cerium sub-group of "Light" rare earth elements (LREEs) which includes La to Eu and the yttrium sub-group of "Heavy" rare earth elements (HREEs) which include the remaining lanthanide elements, Gd to Lu, as well as yttrium (Gupta and Krishnamurthy, 1992, Trifonov, 1963).
An energy dispersive X-ray fluorescence (EDXRF) tri-axial geometry experimental spectrometer has been employed to determine the concentrations of 13 different elements (K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Rb, Sr and Pb) in mine wastes from different depths of two mine tailings from the Cartagena-La Union (Spain) mining district.
The objective of this study was to establish the best parameters to correct for matrix effects in the chemical analysis of a siliceous geologic material rich in metallic elements of high economic value, such as La, Ce, Nd, Sm, and Gd (rare earth elements), using empirical influence coefficients applied to wavelength dispersive X-ray …
An ion-adsorbing type rare earth deposit is normally the weathered crust of a magmatic-type primary deposit. The rare earth elements are adsorbed on the surface of clays in the form of ions. The rare earth elements are not soluble or hydrolyzed in water but follow ion-exchange laws (Lu et al. 1997; Tian and Yin 1996; Li 1993; Chi 1989).
2.2.1 Occurrence. Rare earth minerals occur as fluorites, oxides, tantalates, carbonates, phosphates, sulfates, borates, silicates, etc. (Qi 2018).List of different rare earth minerals are presented in Table 2.3.The average concentration of REEs in the earth's crust is found to be 150–220 ppm, which is much higher than the concentration of other …
