The utility model provides electrostatic powdered gold dressing equipment and belongs to the technical field of dry dressing of powdered gold. The equipment is characterized in that powdered gold falls onto a positive plate of a capacitor of a parallel plate; the powdered gold firstly falls onto an insulated conveying belt in the process of flying to a negative plate after being repelled by electrostatic force; the distance between the insulated conveying belt and a negative pole is 1-10mm, the pole distance is 50-200mm, and the voltage across poles is 30-120kv; the powdered gold on the insulated conveying belt is scrapped off from a scraper blade at a driven roll side and falls into an ore concentrate outlet so as to be discharged; and tailings on a positive pole fall into a tailing outlet so as to be discharged. The equipment provided by the utility model does not use water for dressing, is simple in process and equipment and is easy to popularize.
