Green liquor dregupgraded soils as oxygen barrier in mine waste covers

Publicerad: 3 augusti 2020

An environmental problem arises when sulfide-bearing mine waste is exposed to atmospheric oxygen, sulfides (often iron sulfides) oxidize and produce acidity.

In the absence of alkaline minerals to neutralize this acidity, trace elements including harmful heavy metals may be mobilized and transported as runoff, this is called acid mine drainage (AMD).
