    en.wikipedia.org/wiki/List_of_minerals

    This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species .

  3. Mineral acid - Wikipedia

    en.wikipedia.org/wiki/Mineral_acid

    A mineral acid (or inorganic acid) is an acid derived from one or more inorganic compounds, as opposed to organic acids which are acidic, organic compounds. All mineral acids form hydrogen ions and the conjugate base when dissolved in water.

  5. Organic acid - Wikipedia

    en.wikipedia.org/wiki/Organic_acid

    Simple organic acids like formic or acetic acids are used for oil and gas well stimulation treatments. These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid (HCl) or mixtures of HCl and hydrofluoric acid (HF). For this reason, organic acids are used at high temperatures or when long contact ...

  6. Organic mineral - Wikipedia

    en.wikipedia.org/wiki/Organic_mineral

    An organic compound is any compound containing carbon, aside from some simple ones discovered before 1828. There are three classes of organic mineral: hydrocarbons (containing just hydrogen and carbon), salts of organic acids, and miscellaneous. Organic minerals are rare, and tend to have specialized settings such as fossilized cacti and bat ...

    Other properties can be used to diagnose minerals. These are less general, and apply to specific minerals. Dropping dilute acid (often 10% HCl) onto a mineral aids in distinguishing carbonates from other mineral classes. The acid reacts with the carbonate ([CO 3] 2−) group, which causes the affected area to effervesce, giving off carbon ...

  9. Native element mineral - Wikipedia

    en.wikipedia.org/wiki/Native_element_mineral

    Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. The elemental class includes metals, intermetallic compounds, alloys, metalloids, and nonmetals. The Nickel–Strunz classification system also includes the naturally occurring phosphides, silicides, nitrides, carbides, and ...
