Our continuous countercurrent ion exchange or chromatographic separation systems generate process efficiency that is unrivalled or even impossible with conventional fixedbed systems. PuriTech''s IONIX system offers a lowcost design with a maximum recovery of the minerals, and flexible operation.
Ion exchange usually describes a processes of purification of aqueous solutions using solid polymeric ion exchange precisely, the term encompasses a large variety of processes where ions are exchanged between two electrolytes. Aside from its use to purify drinking water, the technique is widely applied for purification and separation of a variety of .
Strong base anion (SBA) exchange resins are more commonly used for gold extraction. These resins generally contain quaternary ammonium functional groups with fixed positive charges. The ALTA 2014 GoldPM Proceedings 4 gold loading efficiency of these resins is not pH sensitive and they operate effectively across the entire pH range.
Jun 01, 2001· 10 Many solid sorbents have been proposed for gold recovery, including activated carbon, persimmon tannin gel, neem leaf broth, tannin, fungal biomass, and ionexchange resins. 11 Several authors ...

Ion exchange usually describes a processes of purification of aqueous solutions using solid polymeric ion exchange precisely, the term encompasses a large variety of processes where ions are exchanged between two electrolytes. Aside from its use to purify drinking water, the technique is widely applied for purification and separation of a variety of industrially and medicinally ...
Separating soluble substances by interchanging ions. Whereas solids can be separated from liquid media by means of filtration, soluble substances require different means. Ion exchange is the reversible interchange of ions between a solution with soluble ionized substances and a solid (the ion exchange material, such as a cation resin), in which ...
Activated carbon has had a tremendous impact on the technology of gold recovery from leached liquors. Ionexchange resins have been proposed as possible alternatives to carbon, while ionexchange fibers and membranes were investigated recently as adsorbents for metal recovery in view of their fast rate of uptake.
Application of Chelex 100 ion exchange resin for separation and determination of palladium, platinum and gold in geological and industrial materials by neutron activation analysis
Oct 10, 2014· Ion exchange has been widely applied in technology of chemical separation of noble metal ions. This is associated with dissemination of methods using various ion exchange resins which are indispensable in many fields of chemical industry. Due to small amounts of noble elements in nature and constant impoverishment of their natural raw materials, of .
Separation of smaller proteins, peptides, anionic species, and polar molecules. Hypersil GOLD SAX LC Columns A quaternary amino ion exchange ligand ideally suited to separating small polar organic analytes in aqueous mobile phases.
An ionexchange resin or ionexchange polymer is a resin or polymer that acts as a medium for ion is an insoluble matrix (or support structure) normally in the form of small (– mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a large surface area on and inside them .
Dealkalization by weak and strong cation resins is accomplished by exchange of hydrogen ion for hardness ions (and sodium ion in the case of a hydrogen form strong cation resin). Hydrogen ion combines with alkalinity to form carbon dioxide which is removed by .
