This paper is a summary of the author's industrial experiences on the selection andoptimization of flotation reagent schemes for the recovery of gold species. The trends given are acomposite of data and experiences gained on 24 different gold ores from around the globe . The primaryemphasis is on the benefits of matching the associated gold mineralogy to a reagent scheme mostappropriate for that mineralogy. Two general categories are discussed:the foltation of free or native goldspecies and the flotation of gold associated with a variety of sulfide minerals. important plant operatingfactors influencing each of these two categories are presented with supporting examples. Carefullymatching reagent chemistry and appropriate operating conditions to any given gold-bearing ore will notonly lower the total reagent cost but, more importantly, can lead to measurable increases in gold recovery.
