    Inosilicates contain two important rock-forming mineral groups; single-chain silicates are most commonly pyroxenes, while double-chain silicates are often amphiboles. [118] Higher-order chains exist (e.g. three-member, four-member, five-member chains, etc.) but they are rare. [119] The pyroxene group consists of 21 mineral species. [120]

    Mineral processing consists of first liberation, to free the ore from the gangue, and concentration to separate the desired mineral(s) from it. [5] Once processed, the gangue is known as tailings , which are useless but potentially harmful materials produced in great quantity, especially from lower grade deposits.

  5. Mineral resource classification - Wikipedia

    en.wikipedia.org/wiki/Mineral_resource...

    Mineral Resources are further sub-divided, in order of increasing geological confidence, into inferred, indicated and measured as categories. Inferred Mineral Resource is the part of a mineral resource for which quantity, grade (or quality) and mineral content can be estimated with a low level of confidence. It is inferred from geological ...

    Natural resources can add substantial amounts to a country's wealth; [7] however, a sudden inflow of money caused by a resource boom can create social problems including inflation harming other industries ("Dutch disease") and corruption, leading to inequality and underdevelopment, this is known as the "resource curse".

  7. Economic geology - Wikipedia

    en.wikipedia.org/wiki/Economic_geology

    The study is primarily focused on metallic mineral deposits and mineral resources. The techniques employed by other Earth science disciplines (such as geochemistry , mineralogy , geophysics , petrology , paleontology and structural geology ) might all be used to understand, describe and exploit an ore deposit.

  8. Exploitation of natural resources - Wikipedia

    en.wikipedia.org/wiki/Exploitation_of_natural...

    Natural resource extraction and climate change are intertwined in Congo, as mining for copper and cobalt creates a biodiversity loss as green covers are cleared for constructing artisanal mines and roadways. [10] Conflict over resources, poverty, and environmental degradation leaves a large number of the Congolese population vulnerable to ...

  9. Mineral economics - Wikipedia

    Mineral resources are an increasingly valuable commodity within Australia's mining and mineral sector. [4] Australia's largest exports include ‘coal, oil and gas, metals, non-metals and construction materials’, and their mass distribution accounts for a substantial revenue into the Australian economy.
