As environmental regulations become increasingly strict, the neutralization sludge generated in sulfuric acid wastewater treatment has posed a significant problem. How do various companies deal with this neutralization sludge? Are there any manufacturers that sell sludge with Ca and AS contents exceeding 30%?

Someone really does collect them; I have quite a few here.

Why collect this kind of waste? Do you have their contact information?

Some smelters also recycle the neutralization slag, but the fiber mist eliminators need to be replaced with carbon fiber ones

It now counts as hazardous waste and cannot be disposed of casually.
