| The exploitation of
nickel and copper ore at the Lorraine mine
between 1964 and 1968 left over
600 kt of sulphur-rich mine tailings.
The 22-hectare site includes 15 hectares
of mine tailings. Total site restoration costs
were $1.8 million. |
A multi-layer covering installed
to control acidic mine drainage.
|
The spilled tailings were recovered
and the surface of the tailings impoundment was
re-profiled. A capillary barrier covering, generally
known as a multi-layer covering, was established
during the winter of 1999 on the mine tailings
site to control acidic mine drainage, and limestone
drains were set up at the outlet. A program to
monitor system performance and changes in water
quality has been in effect since the covering
was placed in position.
