Tailings ponds are used to dispose of which materials?

• A. Mill wastes from ore treatment processes.
• B. Fresh water for mining operations.
• C. Vegetation debris.
• D. Industrial chemicals only.

Answer: (A)

Tailings ponds are designed to hold the slurry left after ore is processed—the mill wastes from ore treatment. After the ore is crushed and minerals are separated, the residual rock mixed with water and processing chemicals becomes slurry that’s stored in these ponds. The pond lets solids settle and water be recycled for use in operations, making it the appropriate place for this waste material. It’s not meant for pure fresh water, vegetation debris, or chemicals-only waste.
