Hello, there is some arsenic in an oxidized gold ore analysis. It is not in the form of arsenopyrite. I thought it was acting with antimony, but the Sb content is also very low. Could you give an idea what the arsenic here might be acting with?

Other possible arsenic minerals could be Orpiment (As2S3) and Realgar (As4S4). If the ore contents silver, proustite (Ag3AsS3)

Can these arsenic minerals affect the recovery of gold?
