A method of reducing sintering heavy metals emission and recycling heavy metal

The invention discloses a kind of methods for reducing sintering heavy metals emission and recycling heavy metal; belong to metallurgy environment protection and technical field of resource recovery; the sintered material containing heavy metal Pb is carried out after heavy metal cleans in advance again with addition of sintering more particularly to a kind of, while to the method that removal of impurities by-product carries out heavy metal Pb recycling.This method are as follows: the higher sintered material of heavy metal Pb content is removed into soluble heavy metal compound therein by solution cleaning first, is then separated by solid-liquid separation, the solid-phase sintering ingredient for removing heavy metal Pb is separated with soluble heavy metal compound；Sintered material after removing heavy metal Pb enters sintering after desiccation and utilizes；Solution after separation traps heavy metal using trapping medicament, then realizes heavy metal accumulation recycling by being separated by solid-liquid separation；The method provided by the invention for reducing sintering heavy metals emission and recycling heavy metal, may be implemented the emission reduction of sintering process heavy metal and the recycling of heavy metal Pb, reaches the dual purpose of heavy metal emission reduction and recycling, have preferable environmental benefit and economic benefit.
