Abstract:
     This invention is a method using rich sulfur arsenic tin ore debris to produce white arsenic. The main method is to add water, xanthic acid and oils and fats colleting agents and mersolates adjusting agent to implement paste mixing and medical pre-treatment to widen the difference between the arsenic ore and sulfur ore; use floatation machine to floating select and separate to get sulfur refined products and rich arsenic tin debris: use reflecting furnace to oxidation melt the rich arsenic tin debris under 450-800deg.C and make the arsenic matters overflow in the form of arsenous oxide, and use sedimentation and cloth dust collection methods to get while arsenic products and use heavy, magnetic and floating concentration methods to recycle the left tin. This invention adopts the route of devulcanizing first, realize the separation of sulfur and arsenic and oxygenate to get white arsenic and at last choose the qualified tin refined products. The technique flow is short, the design is novel, the methods is proper, and realize the high effective recycle of arsenic, sulfur and tin, and the economic and technological indexes are idea. This invention has a great significance to the utilization of debris resources.
