The result is a simple, low risk technical process for direct recovery. Concurrently, the treatment of the water leach solution was modified to produce a high grade (98.9% total rare earth oxide) product for refining.doi:10.1002/9781119274834.ch1David Dreisinger...
RARE EARTH RESOURCES, THEIR EXTRACTION AND APPLICATION - ScienceDirect TKS Murthy,CK Gupta - 《Science & Technology of Rare Earth Materials》 被引量: 2发表: 1980年 Review of rare earth extraction and product preparation technologies and new thinking for clean utilization application status of ...
There is considerable interest in extraction of rare earth elements from NdFeB magnets to enable recycling of these elements. In practical extraction methods using wet processes, the acid waste solution discharge is a problem that must be resolved to red
A detailed techno economic analysis is also presented in the report for a scaled up geothermal rare earth element extraction process. All rare earth element uptake testing was done on simulated geothermal brines with one rare earth element in each brine. The rare earth element uptake testing was ...
The magnetic nanofluid extraction process for the rare earth metals can be modeled in the diagram shown in Fig. 4. Basically, the magnetic nanofluid is mixed with the feed brine and then the mixture passes through the residence tube to extract REEs. Then the nanoparticles are separated from the...
Quickly becoming a hot-button topic for the South East Asian nation, the Malaysian government recently ordered Lynas to discontinue the extraction process within four years, citing environmental concerns. Seeing the result as a major win, State Premier Mark McGowan said, the decision by Lynas is ...
