Hi everyone. I am trying to figure out how much of the Zn content in waste PCBs is likely to be ZnO. I know the majority of the Zn is alloyed or galvanised steel components. But I have found information that suggests a small amount of the Zn content is in the form of ZnO. I am trying to establish where the ZnO is used and how much is likely to be in there. Thank you very much for nay help you may be able to give me!
