Abstract: A Refractory metal zinc tin ore, lead and zinc recovery after the election of sulfur, sulfur concentrate arsenic exceeded; Carried out after the first magnetic float and float after the first magnetic flow comparison test to determine, After magnetic processing, and one roughing two cleaning two scavenging flotation sulfur, then combined two parts of sulfur concentrate together, got the sulfur concentrate with grade of Sulfur 40.65%, recovery of Sulfur 90.28%, and grade of arsenic 0.37%.

Key words: Separation of sulfur arsenic, Magnetic separation, Combination of inhibitors
