Remediation plans for Boliden

Boliden has closed down its operations at the Långdal and Åkerberget, resulting in a need for remediation plans.

Before the Långdal and Åkerberget mines can be considered to be closed, there must be remediation plans describing how the two areas are to be restored. ÅF helped Boliden with this work.

Work to draw up a remediation plan included both field surveys and planning work. This is because the areas to be treated had to be investigated with regard to how they had been affected by mining operations and how they can then be restored.

Our assignment included the following elements:

  • Characterise the chemistry of waste rock deposited
  • Measure volumes of waste rock deposited
  • Measure volumes of residual ore
  • Summarise a remediation plan including an environmental monitoring programme
