A composite extractant-enhanced polymer resin comprising an extractant and a polymer resin for direct extraction of valuable metals such as rare earth metals, and more specifically, scandium, from 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.

The present disclosure relates, in some embodiments, to a method including demineralizing a protein liquor (i.e., a liquid portion of a lysed microcrop (e.g., Lemna) that has been separated to generate the liquid portion and a solid portion and having a composition including a soluble microcrop protein and a Vitamin B12) to generate a demineralized protein liquor. According to some embodiments, demineralizing the protein liquor may include diafiltration, ultrafiltration, nanofiltration, reverse osmosis filtration, electrodialysis, and/or passing the protein liquor through an ion exchange resin (e.g., an anion exchange resin. a trialkyl ammonium salt having three methyl groups). In some embodiments, a method may further include concentrating a demineralized protein liquor to generate at least one of a milk base and an electrolyte drink.

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.

Provided is a method for purifying a nonaqueous liquid in a simple and cost-efficient manner, without requiring a large amount of the nonaqueous liquid, by using an ion exchange resin having a reduced water content. The method for purifying a nonaqueous liquid using an ion exchange resin includes bringing the ion exchange resin into contact with a nonaqueous liquid for pretreatment having a relative permittivity at 25? C. of 20 or higher and bringing the ion exchange resin after the pretreatment into contact with a nonaqueous liquid to be purified, wherein the relative permittivity at 25? C. of the nonaqueous liquid for pretreatment is greater than the relative permittivity at 25? C. of the nonaqueous liquid to be purified, and the concentration of metals to be reduced in the nonaqueous liquid for pretreatment is 5 ?g/L or less.
