  • Sulfides, Selenides and Tellurides: rebellious and .

    Well, sulfides, selenides and tellurides are simply minerals which contain sulfur, selenium, and tellurium combined with some metal. Unusually this is the metal we are interested in, but sometimes other valuable metals can be mixed in as trace elements. An example of this is when gold occurs disbursed through a crystal of pyrite.

    In the room-and-pillar mining method, minerals are mined throughout a series of rooms, with pillars left in place to hold up the roof. Once a room has been mined, the pillars may remain or be taken out, letting the roof collapse. A disadvantage to this method is that it can leave a large amount of mineral in place.

  • Halite salt: The mineral Halite information and pictures

    Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of salinity content.
