The Smoke Method To Deal With Blast Furnace Lead Smelting Slag Pilot Study

Presently lead metallurgy adopts smelting furnace process in Yunnan. The slags contain metal such as lead/zinc/Indium but some plants are not take order with reclaiming process. Lead slags sometimes contain metal high and the fitted conditions were not eligible, so some plants take order with lead slag lately and make largeness abandon. The lead slags were deal necessarily, in order to realize reutilization of the slag capable of stably satisfying environmental standards and valuable metal can be obtained from slag produced.A good many methods of deal lead slags can be adopted, most leadplants were like to adopt Fuming Process, which process bare big throughput low quality coal is useableness with heat and reducer, on the other side, this craftwork is prone to achieve mechanization automatization, deposed heat make use effectually.This article provides two projects about two lead slags for Yunnan lead metallurgy industry. Lead slags sometimes contain metal high, which slag from blasting furnace smelt in a fuming furnace. This experimentation gives a method for utilizing the slag with fuming process which smelting point can be debased. The experimentation also provides a feasible period and a carbolic wastage by which lead slag containing lead/zinc/Indium having high. One project is 1000g lead slag and 20g carbolic marshal 36gFeO, as temperature 1250℃, fuming 60min, controlling a=l, volatilization rate of zinc reach 83%, and Indium can reach 77%, lead reach 91%.the other is 1000g lead slag and 45g carbolic, as temperature 1270℃, fuming 40min, controlling a=l, volatilization rate of zinc reach 88%, and lead can reach 94%, Indium only reach 50%.Conclusion of experimentation is lead slag silicic acid biggish can be fumed with marshal FeO, and lead slag silicic acid on the small side can be fumed spang.
