DH301 Gold-Selective Macroporous Anion Exchange Resin

DH301 Gold-Selective Macroporous Weak(Medium) Base Anion Exchange Resin A specialty resin for Aurocyanide Recovery Equivalence: Purolite S992,Amberlite IRA96RF.

DH301 is a macroporous-type poly(vinylbenzyl) anion exchange resin tailored for extraction of gold cyanide complexes (aurocyanide) from the pregnant solutions or pulps originated from the alkaline cyanidation of gold ores .

This resin shows high resistance to osmotic and thermal shock and gold selectivity, particularly it has remarkably high selectivity for gold over copper. The resin is also resistant to fouling by the most natural and synthetic organic matter (hydrocarbons). Details of the chemical and physical characteristics are given below. The resin is supplied in bead form with a specially graded particle size required by RIP gold recovery circuits. It can also be used in all known ion exchange contactor designs.

The gold loaded on the resin can be easily desorbed by a few bed volumes, preferably at 40 - 60 °C (104 - 140 °F), of alkaline cyanide solution. No further regeneration is required before the next sorption cycle.
