Data supporting the claim that slag from pyrometallurgical processing is harmless to the environment
Thread Content
I seek guidance from experienced experts regarding pyrometallurgical processing: data on the harmlessness of the slag produced at temperatures above 1200 degrees Celsius (proof).
The slag produced in pyrometallurgical processing is originally ordinary solid waste and is inherently harmful; how can data showing its harmlessness be generated? ? ? ? ? ? ? ? ? ?
Hazardous waste: sludge is incinerated to produce slag, which is sold to brick factories and cement plants for use; moreover, this slag does not constitute hazardous waste； Data (proof) is required to demonstrate the harmless residue resulting from the final thermal treatment of sludge
This requires leaching toxicity tests to be conducted by specialized institutions; it’s quite troublesome.
The slag resulting from the thermal treatment of sludge and sold to cement plants is considered ordinary solid waste; this should already be specified in your company’s environmental impact assessment.
The leaching toxicity test of blast furnace slag can indicate whether the resulting slag is harmless or no longer constitutes hazardous waste Or is the slag considered general solid waste but harmless to the environment?
If the test results show that your slag is harmless, then it constitutes ordinary solid waste.
