Definitions
- the sorbent obtained according to the claimed method has a much greater affinity for scandium than for iron (III) (RU 2531916, 04/26/2013).
- Polymer impregnated sorbents (impregnates) containing extractant and polymer resin are known for extracting rare earth metals, including scandium, from leaching solutions.
- the extractant can be cationic, anionic or non-ionic.
- the polymer resin can be without functional groups or with sulfo groups, carboxyl, iminodiacetic, phosphoric acid or amino groups.
- the method of obtaining the impregnated sorbents includes saturating the polymer resin in the extractant solution, separating the resin-saturated resin from the solution on the filter, and drying the resin-saturated resin to remove solvent residues (WO 2017074921, 04.05.2017).
- TCExs based on di-2-ethylhexylphosphoric acid have a high selectivity and capacity for scandium in the pH range 1, 1-2.0 of the return solution, which allows to reduce the consumption of reagents for pH adjustment, to ensure a high degree of extraction, and obtaining a cleaner end solution of scandium, directed to obtain a commodity compound (RU 2417267, 09/17/2009; RU 2613246, 06/03/2016; RU 2612107, 07.22.2015).
- TBEKS sorbents for the extraction of scandium based on di-2-ethylhexylphosphoric acid, which, by the set of indicators (price, scandium sorption pH, capacity and selectivity), are quite acceptable for production needs.
- TVEX sorbent
- a method of obtaining a sorbent (TVEX) for the selective extraction of scandium including obtaining a starting mixture of components containing an organophosphorus compound (di-2-ethylhexylphosphoric acid), a polymerization initiator, styrene and divinylbenzene, intensive mixing of the mixture and aging followed by raising the temperature to 90 ° C and holding it at that temperature with stirring, cooling the reaction mixture, filtering the resulting product, washing and drying (RU 2487184, 11/03/2011).
- organophosphorus compound di-2-ethylhexylphosphoric acid
- a polymerization initiator styrene and divinylbenzene
- intensive mixing of the mixture and aging followed by raising the temperature to 90 ° C and holding it at that temperature with stirring, cooling the reaction mixture, filtering the resulting product, washing and drying (RU 2487184, 11/03/2011).
