Abstract: A composite extractant-enhanced polymer resist comprising an extractant and a polymer resin for direct extraction of valuable metals such as rare earth metals, and more specifically, scandium, Born an acid-leaching slurry and/or acid-leaching solution in which ferric ions are not required to be reduced into ferrous ions. The extractant may be cationic, non-ionic, or anionic. More specifically, the extractant di(2-ethylhexyl)phosphoric acid may be used. The polymer resin may be non-functional or have functional groups of sulfonic acid, carboxylic acid, iminodiacetic acid, phosphoric acid, or amines. The composite extractant-enhanced polymer resin may be used for extraction of rare earth metals from acid-leaching slurries or solutions.

Abstract: An ion exchange tank is provided. The ion exchange tank includes a processing chamber and an additive chamber separated by a weir system, the weir system having a flow channel fluidly connecting the processing chamber to the additive chamber, wherein the flow is divided from the additive chamber by a first partition and divided from the processing chamber by a second partition, wherein the additive chamber comprises a solids-absorbing material disposed therein.

Abstract: The invention relates to a method of separating and recovering xylose from a xylose-containing plant-based solution. The method is performed in a chromatographic separation system, which comprises one or more weak base anion exchange resins and optionally one or more other resins selected from strong acid cation exchange resins and weak acid cation exchange resins, by passing the solution through the separation system, followed by recovering at least one fraction enriched in xylose. Optionally, a rhamnose fraction may also be recovered.

Abstract: Dispersed solid materials in aqueous waste waters are agglomerated for easier filtering by adding a polyelectrolyte, a floc former and a filter aid in any order in which the filter aid is present for incipient floc formation. The electrolytes exemplified are branch chain amines, quaternary ammonium or sulphonium salts. The floc formers exemplified are tri- and tetravalent metal salts and the filter aids exemplified are diatomaceous silica, perlite, or non-organic fibre.
