Habitat destruction is one of the main issues of mining activity. Huge areas of natural habitat are destroyed during mine construction and exploitation, forcing animals to leave the site. [67] In addition, desirable minerals exist across all biodiversity-rich areas, and future mineral demands are expected to rise. [68]

Evaporite minerals, especially nitrate minerals, are economically important in Peru and Chile. Nitrate minerals are often mined for use in the production on fertilizer and explosives . Thick halite deposits are expected to become an important location for the disposal of nuclear waste because of their geologic stability, predictable engineering ...
The resource curse, also known as the paradox of plenty or the poverty paradox, is the hypothesis that countries with an abundance of natural resources (such as fossil fuels and certain minerals) have lower economic growth, lower rates of democracy, or poorer development outcomes than countries with fewer natural resources.

The halide minerals are compounds in which a halogen (fluorine, chlorine, iodine, or bromine) is the main anion. These minerals tend to be soft, weak, brittle, and water-soluble. Common examples of halides include halite (NaCl, table salt), sylvite (KCl), and fluorite (CaF 2).

Minerals in soils are found in two types; primary and secondary. [5] "A primary mineral has not been altered chemically since its crystallization from a cooling magma." [5] Additionally, a primary mineral is defined as a mineral that is found in soil but not formed in soil, whereas secondary minerals are formed during weathering of
Ferromagnesian minerals are the principal hosts for nickel, cobalt, copper and zinc in sulfide-poor mafic and ultramafic rocks, and are retained higher in the profile than sulfide-hosted metals. [1] They are leached from the upper horizons and reprecipitate with secondary iron-manganese oxides in the mid- to lower saprolite.
