Waste rock
Definition
Waste rock refers to the material that is removed during mining operations and does not contain valuable minerals. It is often piled up near mines and can release harmful substances into the environment.
Analogy
Imagine waste rock as the leftover scraps from a construction project. These scraps are not useful for building, so they are discarded in a pile nearby. Just like waste rock, these scraps can pose a risk if they contain hazardous materials or pollutants.
