Mineral Resource of the Month
The column "Mineral Resource of the Month", featuring the work of USGS mineral commodity specialists, now appears in the American Geological Institute's (AGI) magazine Earth (formerly Geotimes) with selected articles online at the Earth Magazine's Mineral Resource of the Month Archive. For more information about these and other mineral commodities, visit the USGS Commodity Statistics and Information site.

Mineral resource of the month: zirconium and hafnium
Zirconium and hafnium are corrosion-resistant metals that are grouped in the same family as titanium on the periodic table. The two elements commonly occur in oxide and silicate minerals and have significant economic importance in everything from ink, ceramics and golf shoes to nuclear fuel rods.

Mineral resource of the month: wollastonite
When asked about wollastonite, most people respond “wollasta-what?” That’s because the wollastonite industry in the United States is relatively small and not highly publicized. Furthermore, the general public does not have any direct contact with wollastonite despite its use in many consumer products, ranging from car brakes to paint.

Mineral resource of the month: phosphate rock
Phosphate rock minerals provide the only significant global resources of phosphorus, which is an essential element for plant and animal nutrition. Phosphate rock is used primarily as a principal component of nitrogen-phosphorus-potassium fertilizers, but also to produce elemental phosphorus and animal feed.

Mineral resource of the month: steel
About 96 million metric tons of steel was produced in the United States last year — more than any other metal. And the $3.46 billion of iron and steel scrap exported was also the highest of any metal scrap export, helping to reduce the U.S. trade deficit.

Mineral resource of the month: selenium
Selenium is a trace mineral needed in small amounts for good health; however, in any significant amount, it is toxic. As a relatively rare metallic element, selenium has a surprising diversity of uses.

Mineral resource of the month: kyanite
Kyanite and related minerals are used in making refractories, which are materials that can withstand high-temperature environments, generally in excess of 1,100 degrees Celsius. Refractories form an inner lining to furnaces, kilns and other containers with which molten metals and glass come into contact. Fifty to 70 percent of global refractory consumption is related to the steel industry.

Mineral resource of the month: nickel
Together with chromium, nickel makes steel more resistant to corrosion. Stainless steel thus accounts for more than 65 percent of primary nickel consumption in the world. One of the more common grades of stainless steel is Type 304, which contains 18 to 20 percent chromium and 10.5 to 12 percent nickel. Owing to their high corrosion resistance, nickel-bearing stainless steels are widely used in th

Mineral resource of the month: barite
Also called barytes, barite forms in various geologic environments and is frequently found with both metallic and nonmetallic minerals. Most barite is produced by open-pit mining techniques, and most crude barite requires some upgrading to meet minimum purity or specific gravity levels.

Mineral resource of the month: bismuth
Bismuth compounds are most known for their soothing effects on the stomach, wounds and sores. These properties make the compounds an essential part of many medicinal and cosmetic preparations, which until 1930 accounted for about 90 percent of the bismuth used. The subsequent development of low-melting alloys and chemical catalysts containing bismuth, as well as its use as an additive to casting a

Mineral resource of the month: diatomite
Diatomite is a soft, very fine-grained, siliceous sedimentary rock that is usually very light grey or beige in color. It is very finely porous, very low in density and essentially chemically inert. Rocks containing diatomite are excellent reservoir rocks for hydrocarbons.

Mineral resource of the month: lithium
Lithium, the lightest metallic element, is silvery, white and soft, and highly reactive. It is used most frequently in chemical compounds or traded as mineral concentrates. Its thermal properties make it an ideal component in thermal shock-resistant ceramics, and its electrochemical properties make it an ideal material for several types of batteries.
