What is zinc ash and bottom dross loss?  

+++++++

What is the normal ratio of the Zinc ash and bottom dross compared with the consumed Zinc in hot dip galvanization and how I can recover pure Zinc from the ash and dross effectively. I am a manager and producing galvanized wire by hot dip process and the Zinc lost through dross and ash is really bothering me much.So far I remelted the ash (big sizes) in a curicible and recovered metallic Zinc.I have also used ammonium chloride but not found very effective.How can I increase the effectiveness.Is there other additives to mix with the ash and dross?
If you could give me some recommentation it will be very appreciated.

Could you please answer how I can reduce the smoke(fume) created during hot dip galvanization on the Zinc furnace and reduce the zinc ratio retained in the ash?
