Upgrading of Fluosolids Roasting and Acid Making System in Danxia Smelter
Since the original roasting and acid making system in Danxia Smelter is old and has defects in process flow,it cannot meet the calcining demand of the newly-built 100 000 t/a zinc plant and the increasingly strict requirement on safety and environment.After careful assessment,technological transformation is carried out to the system.Now the equipment in the system is mature,reliable and energy-saving,which makes possible the friendly environment and water recycle.
