Full Answer

Copper can be found in crystals or in sometimes quite large masses. It is an excellent conductor of heat and electricity. Only silver is a better conductor, and its rarity and cost are why its use as a conductor isn't more widespread. Copper is one of the few metals that's not silvery or gray. Instead, it's a familiar shiny golden-red color. Its alloys, particularly bronze and brass, are also used in industry and construction.

Silver is rarely found as crystals; it is more often found in wire-like forms and dendrites. It's a soft metal that can be polished to a bright silvery color, but it tarnishes easily. Silver is used in photography, as jewelry, in electronics and as currency.

Nickel-iron is never found in crystals but in great sheets and masses. It's also found in grains enclosed in other minerals. It's fairly hard and becomes harder as the percentage of nickel increases. It's also malleable and magnetic. It's an excellent material for the steel industry.

Platinum is found as grains, plates and sometimes nuggets. A noble metal, it's somewhat hard, malleable, ductile and very heavy. It's used in jewelry and as a catalyst.

  • Q:

    How are rocks different from minerals?

    A:

    Rocks are different from minerals in that minerals are single crystalline accumulations of one or more elements, while rocks are solid accumulations of one or more minerals. Rock can either refer to a particular, detached object or, in a general sense, as a synonym for stone, generally referring to a portion of the substance. Individual minerals can be obvious in rocks, as with granite, or microscopic, as with many basalts.

    What are non-metallic minerals?

    A:

    Non-metallic minerals are minerals that have no metallic luster and break easily. These are also called industrial materials and are typically some form of sediment. Non-metallic minerals are not malleable.

  • Q:

    Where do minerals come from?

    A:

    Minerals come from the Earth’s crust, and they are found in various places throughout the world. Geological processes, such as metamorphic, sedimentary and igneous processes, are responsible for the concentration of minerals. Mineral deposits form into different shapes and sizes depending on the location and process of concentration.
