The present invention relates to a process, method and plant for recovering scandium and ions containing scandium using an ion exchange resin from a feed stream. The feed stream may be, but is by no means limited to, a leach liquor or leach pulp.

Process, method and plant for recovering scandium

A process for removing suspended particles and at least one ionic species from a feed water stream to produce a product water stream, the process includes the steps of forming agglomerates of the suspended particles in the feed water stream; passing the feed water stream containing agglomerated particles through a bed of particulate sorbent material so as to sorb the ionic species from the feed water onto the sorbent to provide a loaded sorbent and filter the agglomerated particles from the feed water using the bed of particulate sorbent material as a filtration medium to load the bed with the agglomerated particles, and thereby produce the product water stream; removing the filtered particles and the ionic species from the filtration medium; and re-using the regenerated sorbent in step b).

Process and plant for treating water

The invention discloses a method for recovering uranium from an acidic leach solution or leach pulp in salt water using an amino-phosphorus resin, wherein the liquid phase of the leach solution or leach pulp contains greater than 3 g/L chloride ion in solution. The resin may comprise a functional group comprising an amino phosphonic group, an amino-phosphinic group, an amino phosphoric functional group and/or a combination thereof. According to the invention the leach solution or leach pulp may be generated by in-situ leaching, vat leaching, heap leaching and/or agitated leaching at ambient, elevated temperature and/or elevated pressure conditions in saline or hyper-saline water.

Method and system for extraction of uranium using an ion-exchange resin

A process for hydro-extracting non-ferrous metals from a slurry, pulp or solution, the process including a resin which is a copolymer of a polystyrene and a non-styrenic polymer, wherein the non-styrenic polymer includes the following subunit: Formula (I) wherein Ris a divalent linking group, preferably alkylene, and most preferably (&#x2014;CH&#x2014;CH&#x2014;; and Ris NH, NR, O or absent. Preferably the resin has an acrylic backbone.

Ion exchange resin and a process for the use thereof

The present invention relates to a method and apparatus for the continuous countercurrent desorption of targeted materials including metals, non-metals and inorganic and/or organic compounds of thereof, wherein the desorption method is divided to the two modes namely: (I) desorption and (II) re-absorption. The desorption of the target material from the loaded resin using the fresh desorbent takes place in mode (I). According to mode (I) loaded resin moves upwardly in a chamber. According to mode (II) impurities are desorbed from resin and targeted material in solution can be re-absorbed. The resin moves downwardly in another chamber during mode (II). Concentrated eluates, which are suitable for the direct economical recovery of chemical elements and/or compounds thereof, can be produced using the present invention. The apparatus of the present invention includes desorption and re-absorption zones that are configured using a 'pipe-in-pipe' construction or a U-shape construction.
