Recycling of clinker of zinc pot
I want to know about recycling of clinker cames from zinc pot Containing high concentrations of zinc,aluminum&lead how it can be recycled?what I need of machines(pots-furnaces.......)?and how can I know that this process is efficient or not ? knowing that concentration of zinc in clinker exceed 64% by weight of the total ash removed from zinc pot ? thanksMahmoud Hamed Ali
At first I thought your clinker was galvanizing dross. After re-reading your question your clinker seems to be ash either "dry" or "wet." Dry ash (as on a dry kettle without any molten top flux) is usually grey colored and can be smelted with a furnace. Recovery is usually 50% to 80% as zinc metal with an iron content about 10 times the zinc bath from which it came. If your clinker is "wet" ash it is primarily black fused zinc chloride within which small balls of zinc are contained. This would come from a wet kettle having mollten topflux on the molten zinc. I am not familiar with methods to reclaim zinc from wet ash.
