Ion Exchange For Recovery The exciting world of kinetic exchange has long been very attractive to LT Technologies as well as our clients. Few technologies are so comprehensive in the way they achieve desired purification with minimal cost and equipment.
Fundamentals of Ion Exchange Ion exchange is the reversible interchange of ions between a solid (ion exchange material) and a liquid in which there is no permanent change in the structure of the solid. Ion exchange is used in water treatment and also provides a method
The ion exchange process, involving the contact of two phases, is a heterogeneous process involving the diffusion (external and internal) of the involved ions and their exchange in …

Ion Exchange Calgon Carbon's ion exchange technology is designed to remove dissolved ionic compounds from water or other liquids. Calgon Carbon offers media, fixed bed and continuous systems for a variety of applications.
Therefore, it is desirable to wash the filtrate cells with water and add the water to the supernatant for subsequent ion exchange recovery. As is conventional, the solution after cell removal is adjusted to a pH of between about 0.5 and 3.0 with an acid solution, for example, sulfuric acid.
Additional information about the recovery of precious metals from acidic halogen leach solutions can be provided by contacting Dow. Plating Baths. Dow's anion exchange resins, such as DOWEX™ 21K XLT Resin, are commonly used in the recovery of gold from spent plating bath solutions.
Ion exchange is a water or wastewater treatment process involving the reversible interchange (switching) of ions between the water being treated and the solid resin contained within an ion exchange unit.
Uranium Recovery (Extraction) Methods Uranium recovery involves one of the following extraction processes. In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits.
Ion exchange is used in nearly every part of the nuclear fuel cycle — from the purification of uranium from its ore to the final recovery of uranium and transmutation products. Ion exchange also plays a valuable role in the management of nuclear wastes generated in the fuel cycle.

An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–0.5 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
A copper recovery ion exchange unit is loaded with ion exchange resin selective for copper. Raffinate is fed into the copper recovery ion exchange unit which is regenerated to recover substantially all copper. A cobalt/nickel/zinc recovery ion exchange unit is loaded with another ion exchange resin selective for cobalt.
Chelating ion exchange resin for resin-in-pulp (RIP) for base metals (copper, nickel, cobalt, zinc) Chelating ion exchange resin for the removal of boron from potable water; Chelating ion exchange resin for the recovery of precious metals, regenerable and non-regenerable
Overview Ion exchange i~ a versatile separation 'proqess with potential forbroad appllcation in the metalfin ishing industry, both for raw material recovery and reuse and for water pollution control.
Abstract. A process was developed for the removal and recovery of high-purity cesium from alkaline waste solutions using the Higgins continuous countercurrent ion exchange contactor.
RECOVERY OF PHOSPHATE FROM SEWAGE SLUDGE AND SEPARATION OF METALS BY ION EXCHANGE Erik Levlin Land and Water Resources Engineering, Royal Institute of Technology, S-100 44 Stockholm, Sweden Abstract Ion exchange can be used to separate phosphorus from iron when phosphorus is recovered from sewage sludge.
For ion exchange, not yet proven at a commercial scale for uranium recovery, the estimated costs are US$33-54 per pound U3O8. Our results suggest that it is technically possible for the United States to recover significant quantities of uranium from current phosphoric acid production.
Precious Metal Recovery - These resin systems can recover gold and other metals from plating operations easily and economically. Select the proper resin for gold recovery from acid or cyanide rinse water. Depth of resin column assures good solution contact for maximum metal recovery. Gold is recovered by incinerating the resin.
Cobalt is generally found as the multi-valent cation, Co 2+, and less often as the mono-valent ion, Co 2+.Both ionic forms can generally be sorbed by strong or weak acid cation exchange resins.

Some ion exchangers from various manufacturers were taken for investigation. These sorbents possess different physical and chemical structure. Their physical-chemical characteristics are summarized in . Table 1. It should be noted that ion exchangers produced by Purolite Com-pany for the first time were used for recovery of plati-num group metals.
Ion Exchange (IX) is a method of removing undesirable metallic salt ions from water by exchanging them with other ions attached to a media or resin. This chemical process occurs because ions have differing affinities for the resin and these ions will replace ions with less attraction as they flow over the media.
Rohm and Haas Ion Exchange Ion exchange introduction 1 FD Sep 2008 ION EXCHANGE FOR DUMMIES An introduction Water Water is a liquid. Water is made of water molecules (formula H2O). All natural waters contain some foreign substances, usually in small amounts.
Ion exchange resins, that are semi-selective for gold, have been extensively used for gold recovery from cyanide leach processes in the former USSR. Despite forward looking statements by researchers and technology vendors, there have been very few applications in Western plants.
