Acid mine drainage poses severe environmental pollution problems due to its high acidity,
toxic metals and sulphate contents. In this review, the available prevention of acid mine …

The oxidative dissolution of sulfidic minerals releases the extremely acidic leachate, sulfate
and potentially toxic elements eg, As, Ag, Cd, Cr, Cu, Hg, Ni, Pb, Sb, Th, U, Zn, etc. from …

Ultrasound-assisted bioacid leaching was examined for the extraction of valuable metals
from spent lithium ion batteries (LIBs). In this work, organic acids in lemon juice were used …

Mine tailings, waste rock piles, acid mine drainage, industrial wastewater, and sewage
sludge have contaminated a vast area of cultivable and fallow lands, with a consequence of …

Biochars have the potential to reclaim mine-impacted soils; however, their variable physico-
chemical properties incite speculation about their successful remediation performance. This …

Mining activities lead to widespread environmental pollution of terrestrial ecosystems due to
the presence of metal (loid) s in tailings. These contaminated areas present a health risk and …

Biochar is considered a promising option for soil fertility improvement, little is known about
its advantage and profitability over other organic amendments in terms of nutrient …

Dumping of acidic mine waste poses severe threats to the ecosystem due to high acidity,
nutrient deficiency and mobility of toxic metals. The present study has been undertaken on …

The addition of biochar in acidic mine spoils contaminated areas has been suggested for
buffering and improving the fertility as well as the reduction in the metal bioavailability. This …

Soil enzymes are crucial for soil nutrient cycling function. Understanding of the factors that
control their response to major disturbances such as dumping of environmentally toxic acidic …
