Ranking factors for difficult mineral

  1. Rarity
    The primary factor to consider is the rarity of the mineral. Minerals which have been found in only a few locations or in very limited quantities are considered more difficult to find.
  2. Geographic distribution
    The geographical distribution of the mineral should be taken into account. Minerals that are found in remote, inaccessible areas, or that require extensive exploration, will be more difficult to locate.
  3. Formation conditions
    Some minerals form only under very specific conditions, such as high pressure, temperature, or within specific types of geological environments. These factors can make certain minerals more difficult to find.
  4. Economic value
    Minerals that are highly-valued and commercially-important have a higher chance of being discovered due to the incentive for mining companies to invest in exploration. Less valuable minerals may be overlooked and hence more difficult to find.
  5. Crystal habit and appearance
    Minerals that have distinctive crystal habits and physical properties may be easier to identify and find, while those with similar appearances to more common minerals may be more difficult to pinpoint.
  6. Extraction challenges
    Some minerals may be difficult to extract from their host rocks, requiring specialized mining techniques or advanced technology. This can increase the difficulty in finding and collecting a particular mineral.
  7. Legal and environmental constraints
    Some mineral deposits may be protected by law or located in areas with strict environmental regulations, making it more challenging to access and collect them.
  8. Cultural and political factors
    Difficulty in finding certain minerals can also be influenced by cultural attitudes, local beliefs, or political situations, which may restrict or limit access to particular regions or mineral deposits.
