Hi,all.
I have a bucket of waste filter papers.I collect them for a year.Some of them are waste from filtration silver nitrat,and the rest are from aqua regia filtrations.
I want to recover some gold or silver or other PM that may still there.But I never do this before.So,please help me.Give me a advice about the process.Do I need to incinerate them first?or process them directly with chemicals?
Best regards.
