Effect of arsenic-antimony mineral on cyanide leaching_

 · Effect of arsenic-antimony mineral on cyanide leaching. Arsenic in gold ores exists in the form of sulfides (realgar, orpiment, arsenopyrite, etc.). Arsenic minerals are extremely harmful to the leaching of gold and silver, sometimes making them impossible to carry out. Realgar (As2S3) and orpiment (As2S2) are highly soluble in alkaline cyanide:
