How to control the zinc oxide content in the production of zinc chloride using the zinc calcine method?
Thread Content
We use hot-dip galvanizing zinc soil and dust collected from dust removal processes (in small quantities) as raw materials, and produce zinc chloride using the zinc ore roasting method. However, the zinc oxide content remains around 2.2, while the standard requires it to be below 2.0. Could you tell me what might be causing this problem? Are there any ways to control the zinc oxide content? The lower, the better. Is it possible to add salts or acids before roasting in order to reduce the pH and thus lower the zinc chloride content? Thank you! reward_7ree
Since I’m not familiar with the relevant processes and techniques, I don’t know where the problem lies either

Why is there no one? ? Really, no one knows?
