Environmental Risks of Mining

Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and ... Learn More

3. The Environmental Impacts of Aggregate Extraction

A more detailed picture of the environmental impact of aggregate mining is outlined in a 2005 legal challenge to the expansion of an existing quarry in the Niagara Escarpment.
