MINERALS OF COMPANY


NATURAL GRAPHITE
Mineral Name:
Mineral Detail:

MINERALS NATURAL GRAPHITE Graphite is rather common, but fine crystals are rare. Most Graphite mining areas produce enormous quantities from a single or several large Graphite veins. Graphite has the same chemical composition as the mineral Diamond, but the atomic structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties. Much care should be given to Graphite specimens, especially thin crystals, which are fragile. It is very hard to wash crystals as they peel off and get ruined. Graphite will also smudge on its surface, and can get worn out if it is moved around too much. Graphite also smudges the hand if handled, and will smudge a paper or cardboard box if it is stored in one. The "lead" in pencils is in fact composed of a mixture of Graphite and clay. There is no lead in pencils at all. Much of the commercially mined Graphite is used for pencil fillings. Its main function, however, is as a lubricant. It has many electrical uses, primarily because it is the only common nonmetal that is a good conductor of electricity.


KAOLIN & OTHER KAOLIN CLAYS
Mineral Detail:

MINERALS KAOLIN & OTHER KAOLIN CLAYS Kaolin is a very common mineral. Kaolin is a soft, earthy, usually white mineral, produced by the chemical conditioning of aluminum silicate mineral. Kaolin is used in ceramics, medicine, bricks, coated paper, as a food additive, in toothpaste, as a light diffusing material in white incandescent light bulbs, and in cosmetics and as a filler in many other applications. Kaolin has even been used for spiritual and healing purposes! It is also being formulated as a spray to be applied to fruits and vegetables to prevent insect damage and infestation. The largest and most common use is in the paper industry. It is the main ingredient in creating "glossy" paper. Other materials such as calcium carbonate (which is an alternative material) competes with Kaolin as the most important source/ingredient for creating shiny paper.
