Arsenic mine tailings and health Better Health Channel

Arsenic is a substance found in the environment. It occurs naturally in crushed rock. It is often found near gold deposits and is extracted as part of gold and other mining activities. The waste left over after mining processes is called mine tailings. Mine tailings often look like fine clay or sand and commonly contain raised levels of arsenic.

DST signs contract with Quebec Developer for Arsenic

The arsenic concentration within the dusts is known to be between 40 and 60%, mostly in the form of arsenic trioxide. The arsenical dusts also contain a gold content up to 10 g/t of gold. The gold recovery will be investigated, qualified, and quantified as a mean of offsetting the remediation costs associated with the stabilisation of the arsenic.
