Etching waste liquid
Thread Content
Hello everyone, I have some questions I’d like to ask. My company has alkaline etching waste liquid, and the copper in it has been removed; basically, there is no copper left in the waste liquid. Do you know of any methods to deal with this? Is there anyone who recycles these waste liquids? Our company can even provide it for free, but you will need to arrange transportation to take it away yourself? About 35 tons per month.
Where is your company located? What are the basic components of waste liquid? Is it convenient to talk about it?
What are the components, and are there any other metals included? . . . . .
Alkaline etching solutions can be regenerated and reused for etching directly after copper has been extracted from them. Doing this is both wasteful and unsustainable.
It’s interesting to see how copper is extracted. Currently, extraction methods such as solvent extraction and electrolysis are used. The waste liquid resulting from copper extraction can be reused for etching circuit boards after being processed. This waste liquid mainly consists of ammonia water, ammonium chloride, and various additives; if it isn’t reused, it is necessary to pay a qualified company to handle it
