Mineral Resource of the Month: Cesium

Cesium, an alkali metal that is slightly golden in color and melts in one’s hand, is one of only two metals (along with mercury) that are liquid at room temperature. It is not found in nature in its elemental state because it is easily oxidized.

Mineral Resource of the Month: Asbestos

Asbestos is a generic name given to six needle-shaped minerals that have been used in commercial products. It is an industrial term rather than a mineralogical term, referring to specific fibrous mineral particles that possess high tensile strengths, large length-to-width ratios, flexibility and resistance to chemical and thermal degradation. Asbestos also exhibits high electrical resistance, and many forms can easily be woven into textiles. Even though asbestos markets have declined dramatically over the past 30 years because of health and liability issues, it is still used throughout the world.

Mineral Resource of the Month: Iron Ore

In nature, elemental iron is found largely in either magnetite or hematite, both iron ore minerals. Nearly all iron ore — whether used directly as lump ore or converted to briquettes, concentrates, pellets or sinter — is used to make steel. In the United States, steelmaking accounts for almost 99 percent of iron ore consumption. Minor amounts are consumed in the production of cast iron, cement, magnets and jewelry. There are eight major iron ore mines in the United States — all surface mining operations — two in Michigan and six in Minnesota.

Mineral Resource of the Month: Diamond

Diamond is an extremely stable form of carbon: It is a material with superior physical properties due to the very strong covalent bonding between the carbon atoms. Diamond has the highest hardness and thermal conductivity of any known natural or synthesized material. In diamond, the carbon atoms are arranged in a rigid cubic crystal structure called a diamond lattice — it is this lattice that blocks impurities, thus giving diamond its colorless appearance.

Mineral Resource of the Month: Zinc

Zinc is the fourth most-widely consumed metal, following iron, aluminum and copper. The Romans were the first to use zinc. To produce brass, they smelted copper with calamine (a zinc ore) to make an alloy more golden in color than bronze (a copper-tin alloy), which they called calamine brass. They were unaware zinc was involved.
