Mar 04, 2013· Honda Motor established the world's first process to reuse rare earth metals extracted from nickelmetal hydride batteries for new nickelmetal hydride batteries to .
General description of the process. The first step of an extraction process is mixing for an intensive contact of both liquid phases to enable the mass transfer of the product (white dots) from the (blue) feed liquor into the (yellow) solvent. The second step is the phase separation or settling of the 2 liquid phases.
"The results suggest that at equivalent molar concentrations of 220 mM the biolixiviant was more efficient at rare earth element extraction than gluconic acid and phosphoric acid but less efficient than sulfuric acid. Unlike the organic acids, at pH the mineral acids failed to extract REE, likely due to different complexation and kinetic ...
Mar 21, 2012· Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.
After many years of research and development, the wet separation technology of rare earth is becoming more and more perfect, especially the extraction and separation technology that using P507 Extractant, which has completely reached the production requirements of continuous, stable and addition the selection of process, extraction equipment is also very important.
Abstract The solvent extraction of neodymium, a rare earth metal, was studied with a continuous stirred vessel. One of the widely used extractants, 2ethylhexyl phosphonic acid mono2ethylhexyl ester (PC88A), diluted with kerosene was selected as an extracting organic solvent.
Abstract The proposed process approaches the problem of solubilizing rareearth phosphates (monazite and xenotime) found at the Pea Ridge iron mine in Sullivan, MO, from both a pyrometallurgical and hydrometallurgical point of view. It utilizes a roasting operation that converts the rareearth phosphates to rareearth oxides (REOs), which eliminates some costly and hazardous processing steps ...

The Company has developed a rareearth extraction process and business relationships with the potential to deliver significant nearterm rareearth production outside of China. Rare earths are critical inputs to all modern computing and electronic products, as well as wind turbines, electric and hybrid vehicles, and strategic defense systems.
In a laboratory scale test with a fractional extraction process, yttrium was separated from all the other rare earths with the CA12TBP and HABTBP system to obtain Y2O3 product of % with a yield of 95% and Y2O3 of % purity with a yield of 95%, respectively[74,79].
Oct 13, 2012· The oil extraction process is only the first step in creating cleaner energy for the planet. When the oil extraction process ends, it needs to be refined so the extracted oil ends up in an oil refinery where chemists remove the impurities. This entry was posted in Oil Extraction Process.
