Study About The Properties And Cyanide Leaching Experiment Of The Gold Ore From Dapingnanshan

In recent years, the global resources are becoming less and less, the mineralresources reserves are raning out, the difficult processing resources that cannot bedeveloped in the past years are being developed. This thesis mainly forcuses onstudies on the sodium cyanide effect on gold ore cyanide leaching. The role of sodiumcyanide in the cyanide leaching processes was studied, and various factors thatinfluence the cyanide leaching processes were also detailed invesitigated.Cyanide leaching of gold ores including that from DaPingNanshan area inHeilongjiang province was studied. Different processing methods were adoptedaccording to the different ore properties. Good experimental results were obtained.
