The synthesis, characterization, and application of ...

The genesis of the chelating Ion-exchange resin can be traced to Griessbach who in 1939 proposed the synthesis of a series of ion-exchange resins with varying acidic strength which would show selectivity toward particular ions (1-2). Erlenmeyer and Dahn (3) first demonstrated the useful­ ness of a chelating resin in their separation of various

Recovery of gold from chloride solution with ion exchange ...

The extraction of gold from chloride solutions by ion exchange is examined. It is shown that at initial gold concentrations between 1-5 ppm, 20 g/l Cl-and pH 5, the kinetics of loading on weak base resins are slightly slower than those observed with activated charcoal. Equilibrium loading of auric chloride varies considerably as a function of pH from one resin to another.

New Developments in Ion Exchange Resins for the Recovery ...

Gold-selective ion exchange resins have been designed to have a high selectivity for the mono­valent Au(CN) 2 - (and Ag(CN) 2 - ) species. Any other metals that forms similar complexes, such as Cu(CN) 2-, will compete for active sites on the resin and reduce the resin's capacity for precious metals. Ion Exchange Resins Versus Activated Carbon

Ion-exchange resin - Wikipedia

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 (0.25–1.43 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 …

Sequential recovery of gold and copper from bioleached ...

Herein, we demonstrate effective recovery of bioleached Au and Cu via selective separation using ion exchange resins. pH-edge experiments revealed high affinity of Amberjet™ 4200 resin towards Au (adsorption capacity > 98%) over the entire pH range from pH 2-10, whereas Amberlite IRC-86 resin recorded very high Cu adsorption at around pH 5.

Ion Exchange Resins - OZIRA PTY LTD

Ion exchange resins basically work on the principle of ionic equilibrium and selectivity. In most cases this is a reversible chemical reaction where dissolved ions/contaminants (Cations, Anions, Organics) are removed from solution and replaced with counter ions in the resin structure.

SELECTIVE RECOVERY OF GOLD FROM HYDROCHLORIC …

Ion-exchange resins are very scarcely used in the commercial extraction of gold from hydrometallurgical solutions, in spite of the advantaged offered by resins (higher loading rate, easier gold elution, etc.) as compared to active coal [10,11]. However, the application of ion- exchange resins for gold separation from
