A refractory gold ore can be defined as any ore that responds poorly to a conventional gravitycyanidation process with examples often including copper porphyry complex sulfides arsenopyrite and leadzinc associations an increase of 1 in overall plant recovery can be expected Carbon in Leach CIL Adding activated carbon3254
Oct 20 2014018332The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon typically 10004000 gt At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and4205

The original process plant commissioned 1997 design was a 1 Mta twostage crush singlestage grinding circuit with gravity separation and tabling of concentrate The classified mill product fed a trash screen that feeds a carboninleach CIL train The leach tails were deposited in a traditional paddock style tailings storage facility TSF4786
Jan 01 20160183321 Background For the past 100 years the key element in the processing of gold ore has been the cyanidation process Over the years steady improvements have occurred in equipment design milling has evolved from stamp mills through tube mills and ball mills to the large semiautogenous grinding SAG and fully autogenous grinding FAG circuits in modern gold plants3468
A high grade of gold on the carbon and a high gold recovery are obtained by stagewise adsorption and a countercurrent ow The carbon in the rst CIL tank thus contains the highest grade of gold 3 Carbon elution Loaded carbon from the st CIL tank is transferred by a slurry pump to the loaded carbon4171
adsorption onto activated carbon these effects include competing metalcyanide complexes pregrobbing and the mineralogy of the ore This thesis considers these areas from an experimental and modelling viewpoint In this research it is shown that a variety of metalcyanide species can be used to leach gold from certain refractory ores4647

Provided is a method for treating refractory goldbearing ores that have both sulfide material with which the gold is associated and from which the gold is difficult to separate and having organic carbonaceous material having an affinity for at least one of gold and a gold complex The mineral material is pressure oxidized in the presence of a halogencontaining material in a manner to reduce4899
Recently the US Bureau of Mines examined the recovery of gold by chlorination of refractory carbonaceous and sulfidic ores comparing various treatment methods in which a ground ore pulp is contacted with chlorine gas and activated carbon is added to the pulp for a carboninchlorine leach CICL The objective of this research was to demonstrate the basic feasibility of CICL technology4943

Refractory gold ores are those that do not yield high gold recoveries in conventional cyanide leaching circuits even when the ore is finely ground flotation where gold can be concentrated in a small mass pull and reduce size and cost of a plant 6 continued to leach at a slower rate with some evidence of gold loss from solution4104
