| titleOfInvention | A method of recycling valuable metal and arsenic harmlessness disposing from arsenic-containing smoke dust |
| abstract | The present invention relates to a kind of methods recycling valuable metal and arsenic harmlessness disposing from arsenic-containing smoke dust, include the following steps：Normal pressure water logging；Leachate catalysis oxidation；Oxidated solution consolidates arsenic；Leached mud washs；Washery slag recycles valuable metal.Method provided by the invention passes through normal pressure water logging, remove solvable arsenic in flue dust, trivalent arsenic is pentavalent arsenic through catalysis oxidation in leachate, the solid arsenic mineral of arsenic synthesis stabilization in oxidated solution, then cure solid arsenic mineral by the way of stockpiling or cement solidification, leached mud is washed, reduction melting, aoxidizes the processes such as blowing, maximizes and recycles each valuable element.Arsenic is removed from flue dust, and makes antimony, lead, bismuth etc. and stayed in as far as possible in dearsenification slag by the method, realizes that the separation of arsenic and valuable metal is simultaneously innoxious.Comprehensive resource utilization rate of the present invention is high, and raw material wide adaptation range solves the flue dust generated in pollution problem in traditional handicraft extraction process, especially Lead-Zinc Sintering Process, and the advantage of this method is more obvious. |
