Abstract

Resin-in-leach (RIL) cyanidation experiments were performed on a refractory carbonaceous gold ore to determine if strong-base ion exchange resins could absorb the soluble aurocyanide complex in preference to natural preg robbing organic constituents. Direct cyanidation of the ore resulted in less than 2% gold extraction in 24 hr.RIL cyanidation resulted in about 70% gold recovery onto the resin. Kinetic experiments indicated that 50% of the gold is extracted after 1 hr of leaching. Resin breakage was investigated for as-received and preattrited resins. Similar results were obtained with three different strong base resins. Amberlite IRA-400, Amberlite IRA-900, and Amberlite XE-834.
