  • Ion-Exchange Methods of Scandium Recovery from

    Abstract—The extraction of scandium from a nitric acid solution after pressure leaching of the hydrate cake that forms upon processing the ore of the Tomtor deposit is studied. The main technological laws of scandium sorption and extraction using various absorbers under static and dynamic conditions are investigated. To extract scandium, we recommend using phosphorus-containing cation

  • An innovative process for extracting scandium from

    2020-1-1 · A two-stage process was developed to recover scandium from laterite ore. • Scandium was concentrated in a slag phase using carbothermic reduction process. • Scandium was then leached using NaOH cracking process. • Statistical analyses were used to

  • Research on Scandium Recovery and Extraction

    And attention is being paid to study the effect of Na2S concentration and pH on Pb (Ⅱ) removal rate with Na 2 S as EDTA regeneration medium. The results obtained demonstrate that when the liquid-solid ratio is 10, EDTA concentration is 0.5 mol/L, extraction time is 24 h, extraction efficiency can reach 66.67 %.

  • Scandium of the Kovdor

    2016-1-1 · In the case of scandium recovery on the “Kovdorskiy GOK” ore processing plant, such occasions would produce an economic effect similar to that of bonanza in vein gold deposits. As baddeleyite is the main concentrator of Sc, resources of the metal are estimated in proportion to ZrO 2.

  • Why Scandium Solvent Extraction Is Better Than

    2021-6-20 · Scandium Recovery Utilising Solvent Extraction. Scandium can be recovered by a range of common solvent extraction reagents. The same applies to a range of ion exchange resins. Often these reagents extract scandium quite selectively at low pH, eliminating the need for neutralisation of the leach solution prior to scandium recovery.

  • Scandium: Ore deposits, the pivotal role of magmatic

    2020-12-2 · Abstract. Scandium (Sc), known as the “miracle metal”, has unique properties in material sciences, and is a critical resource in the world due to the low supply but wide applications in advanced technology. Although not extraordinarily sparse in the Earth’s crust, Sc is often dispersed and does not form ore deposits.
