STUDY ON GOLD LEACHING OF HIGH ARSENIC GOLD ORE

Leaching behavior of gold arsenic gold ore was compared by different methods of preliminary treatment in this paper,arsenical removal effictiveness from high arsenic gold ores and cause affecting leaching rate of gold was researched.It was approved that the ammoniac thiosulfates sodium solution is very excellent reagents for leaching gold from height arsenic gold ore,this method can omit the complicated processes of variety preliminary treatment,and leaching rate of gold can be raised from routine method of cyanid leaching 15% to approximate 90%.
