| titleOfInvention | A kind of method that gold, carbon, sulphur and element silicon in Carbonaceous gold ore are recycled in comprehensive cleaning |
| abstract | The invention discloses a kind of methods of gold, carbon, sulphur and element silicon in comprehensive cleaning recycling Carbonaceous gold ore, including sodium hydroxide and Carbonaceous gold ore are sufficiently mixed pelletizing, sulphide ore is decomposed by high-temperature roasting, carbon is oxidized, make to be wrapped in sulphide ore and sufficiently exposed by the gold particle of carbon adsorption, improves the leaching rate of gold.Carbon, the oxysulfide of generation can be used for preparing the stabilizer that non-cyanogen leaches.Fired slags carry out high pressure-temperature water logging, generate sodium metasilicate, promote gold particle exposure, improve the golden efficiency of subsequent leaching.Filter residue is by non-cyanogen reagent and stabilizer Leaching of Gold.Present invention process is simple, and gold recovery is high, carbon, sulphur, element silicon element in raw ore is rationally utilized, and obtain by-product sodium metasilicate, improves comprehensive benefit, technique is environmentally protective.Gold recovery reaches 90% or more, 99% or more the silicon rate of recovery, carbon, 95% or more sulfur recovery rate.This technique has a extensive future, and resource utilization is high. |
