Overall Treatment of Process Effluent from Ammonium Molybdate AITranslate
Abstract AITranslate
Study is made of the treatment of acid effluent from ammonium molybdate plant by addition of ammonium sulfide and pH value control with ammonia spirit.Under proper condition,over 90% of heavy metals Cu,Pb,Zn,Fe in the effluent are precipitated and removed,>98% Mo coprecipitated into the residue.Then,the precipitation residue is dissolved by ammonia spirit with 84.59% Mo converted into ammonium molybdate solution,while Fe,Cu,Pb in the residue are basically insoluable,part of Zn going to ammornium molybdate solution ,which can go directly back to the main circuit of ammonium moybdate.The treated acid effluent is retreated for removal of alkali metal ion before crystalized to produce ammonium nitrate.
