Method for synergistically smelting arsenic alkali residue leaching residues and tungsten-containing waste residues
The invention discloses a method for synergistically smelting arsenic alkali residue leaching residues and tungsten-containing waste residues. The method comprises the following steps: crushing and grinding arsenic alkali residue leaching residues and tungsten-containing waste residues, mixing with a carbonaceous reducing agent, a silicon dioxide substance and a binder, granulating, roasting the obtained granules, recovering arsenic and antimony components from roasting flue gas in the roasting process, recovering a sodium tungstate product from a roasting product through water leaching, and taking the remaining solid as a ceramsite product. According to the method, harmless removal of arsenic and resource recycling of antimony in the arsenic alkali residue leaching residues can be achieved, meanwhile, resource utilization of tungsten in the tungsten-containing waste residues is achieved, ceramsite products with additional values are obtained, and resource utilization of the arsenic alkali residue leaching residues and the tungsten-containing waste residues is truly achieved.
本发明公开了一种砷碱渣浸出渣与含钨废渣协同冶炼的方法。该方法是将砷碱渣浸出渣和含钨废渣经过破碎磨矿后,与炭质还原剂、二氧化硅类物质及粘结剂混合造粒,所得粒料进行焙烧,焙烧过程中从焙烧烟气中回收砷锑组分,焙烧产物经过水浸回收钨酸钠产品,余下固体作为陶粒产品。该方法能够实现砷碱渣浸出渣中砷的无害化去除和锑的资源化回收,同时实现了含钨废渣中钨的资源化利用,并获得具有附加值的陶粒产品,真正实现了砷碱渣浸出渣与含钨废渣的资源化利用。
