Processing Galena Ore For Gold

from gold ore to dor,from ore to dor cyanidation more gold is recovered by cyanidation than by any other process. in cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. when gold dissolution is complete, the gold-bearing solution is separated from the.how to set up an eco-friendly gold processing plant,  traditional gold processing methods generally use the toxic chemicals cyanide or mercury as reagents to extract gold particles from ore, exposing miners and the environment to toxic waste and gases. in contrast, clean mining offers an environmentally-sound gold processing technology that uses an inorganic compound, thiosulphate, in the place of toxic chemicals..

Gold Processing 101

  metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: bashing (crushing); mashing (grinding); and. hashing (extraction/recovery) in the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.
