How to dispose of molten copper?
Thread Content
Our factory has replaced the refining copper washing process with the alcohol hydrocarbonization process. The copper washing section device and the copper liquid in the device are idle. The main problem is that the copper liquid must be inspected to avoid leakage and excessive external drainage. Excuse me, how to dispose of this part of copper liquid?
It can be recycled (depending on the concentration and availability of the solution), or its precipitate can be removed by coagulation and filtration.
Copper is a good thing, of course it must be recycled, which is also right* * A call for energy conservation, emission reduction, and circular economy. If there are other substances in the copper liquid, they can be treated through physical, chemical and biochemical methods. Generally, the copper liquid can be discharged after recycling the metals through physical and chemical methods and adjusting the PH value. However, if it contains a large amount of oil or other organic matter and the COD exceeds the standard, it needs to be reprocessed by biological methods before being discharged.
Generally, the sacrificial anode method is used, for example, iron or zinc is used to replace copper ions, and then counter-iron or zinc ions are precipitated to purify water and protect the environment.
After adjusting the pH value with alkali solution, add excess iron filings to replace the precious metal copper in the wastewater, and then adjust the pH value to be greater than 8 (at this time, the solubility of copper hydroxide is less than 0.1mg/l). Basically, the discharge can reach the standard. And can recover the copper in the solution
We are contacting the manufacturer that sells copper wash, give it a try! I want a lot!
You can consider adding acid to prepare copper sulfate, which is the pesticide Bordeaux mixture.
What are the main ingredients? According to the form of copper, choose the appropriate recovery method. You can try to select the appropriate flocculant after adjusting to the appropriate pH conditions, precipitate it, and then further process or sell it.
