Environmental Impacts of Sand and Gravel Operations in New

The most obvious environmental impact from aggregate, stone, and industrial mineral mines is degraded air quality, and associated health effects, resulting from airborne emissions from both the stack and the disturbed areas at these mines. In an arid landscape like New Mexico, the impacts of such mines on surface and groundwater quality is not likely to be significant.

Tailings Wikipedia

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining

The Environmental Impacts of Aggregate Extraction

extraction is the altering of landscapes and degradation of the environment. However, before an aggregate resource can be developed, the extraction site must qualify for all necessary permits and the approving officials must be convinced that the operation can take place without adversely affecting the environment (E-laws, 2004).

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.
