Management of tailings and waste-rock in mining
activities

• Why ?
• EC communication of safe operation of mining
  activities.
• technical document to try and avoid similar
  accidents in future
• similar to Aznalcóllar and Baia Mare.

Typical Components of a Mineral Processing
Facility

• In-pit crusher
• Feed from stockpile or coarse ore bin
• Comminution (size reduction by crushing and
  grinding)
• Classification (e.g. screens or cyclones)
• Separation (e.g. flotation, gravity, magnetic,
  electrical separation)
• Dewatering (e.g. thickeners (outside), filters
  (usually inside)
• Storage or Shipping of Concentrate (separate
  building)
• Tailings to Tailings facility

Coal

• Only if its processed and there are tailings
• (following theme)
• Therefore generally
• - Hard Coal (Rock Coal) covered
• - Lignite (Brown Coal) if processed and tailings
