• qualities of a mineral that classify it as ore

    23/06/2017 · The qualities of a mineral that classify it as an ore are usefulness and profitability. Explanation; Minerals refers to naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores on the other hand are concentrations of minerals in rock that are high enough to be economically extracted for use.

  • Classifiion of Ore Deposits

    12/02/2017 · The genetic classifiion should ultimately determine the limits of ore deposition in each class by temperature and pressure. Each deposit should be considered as a problem in physical chemistry, and the solution of this problem, with the necessary geologic data, will suffice to fix the mode of formation of the deposit.

  • Mineral Ore Deposits: Meaning, Origin and Types | Geology

    In another common method of classifiion, ore minerals are divided into hypogene (also termed primary) deposits and supergene (also known as secondary) deposits. The secondary deposits are formed as alteration products of primary deposits through weathering and related processes. An ore deposit may be either of igneous or of sedimentary origin.

    Mineral Mineral Classifiion of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (, halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...

  • Mineral Groups – Physical Geology

    Mineral Groups Most minerals are made up of a ion (a positively charged ion) or several ions and an anion (a negatively charged ion (, S 2–)) or an anion complex (, SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the ion is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their predominant anion or anion group.
