Solvent extraction experiment of Sc was investigated.The extraction system consisted of 25% TBP+60% sulfonated kerosene +15% reforming agents. The results show that the extraction rates of Sc can reach up to 95%.The removing of Fe,Mn and Ti can be reached 99.1%, 99.4% and 99.5% respectively.The anti-extraction rates from organic phase with NaOH reach up to 99.7 % with effective separation ...
Study of adsorption behavior of a new synthesized resin ... However, the industrial application of scandium is still limited because its extraction and separation from ores is difficult (Xu et al., 2013). The scandium content in rare earth minerals, such as monazite and bastnasite, is in the range of 20 to 50 ppm (Wang et al., 2011).
Nigel Ricketts, our Process Engineering expert and Manager of Studies in Queensland, recently presented a paper at TMS 2019 in Texas on scandium solvent extraction. If you are a process engineer interested in scandium processing techniques, or a mining professional looking at scandium opportunities, this condensed version of the technical paper might be of interest to you.

Extracting 2 percent of the available REEs would provide an economic boon to companies, the team said. "We were able to very easily extract 0.5 percent of REEs in this preliminary study using a basic ion exchange method in the lab," said Pisupati. We are confident that we can increase that to 2 percent through advanced ion exchange methods."
