Resumo

This chapter gives an overview of the development of anion-exchange resins for the recovery of gold cyanide from cyanide leach liquors in resin-in-pulp (RIP), resin-in-leach (RIL) and resin-in-solution (RIS) circuits. Three gold-selective anion-exchange resins are currently available commercially— namely, Minix, AuRIX, and AM2B. RIP has also demonstrated, during laboratory and plant evaluations, to be a stronger adsorbent for the recovery of gold from preg-robbing ores and that recovery of gold could be improved when RIL is used instead of carbon-in-leach (CIL). This aspect, together with the fact that resin is stripped at relatively low temperatures and pressures, and does not require thermal regeneration, would potentially make the RIL circuit significantly more profitable than CIL.
