Evaluation of Arsenic Leaching Potential in Gold Mine ...

• Peat amendments enhanced the leaching of As from gold mine tailings. • Amendments of 5% peat promoted As(V) leaching, whereas 10% peat increased As(III) leaching. • As(III) was predominant at 20 mg L³−1 dissolved organic C from peat. • Mine drainage treatment sludge could decrease As concentra-tions by 65 to 80% in tailings’ pore water.

Peat and mine drainage treatment sludge can be valorized as amendments on mine sites to stabilize gold mine tailings and reduce the potential leaching of contaminants in pore water. However, the influence of organic amendments on the mobility of metalloids and/or metals in the tailings must be validated, as the leached contaminants may vary according to their type, nature, and origin.

Tailings - Mt Todd Gold Mine

Tailings are the product of processing ore to recover the contained metals. After extraction from the mine, the ore is crushed and subsequently ground to a particle size that allows for the liberation of the metals from the host rock. Most mineral deposits are composed of many different minerals, some of which contain metals.
