Kaolin

In 2005, 22 companies mined kaolin in nine US states. Production in Georgia declined to 6.19 Mt down from 6.78 Mt in 2004. Despite the decline, Georgia remained the leading producer state followed by Alabama, South Carolina, Arkansas, Texas, Nevada, California, North Carolina and Florida. In the next year or two, domestic and export sales of...

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: beryllium

Beryllium metal is lighter than aluminum and stiffer than steel. These and other properties, including its strength, dimensional stability, thermal properties and reflectivity, make it useful for aerospace and defense applications, such as satellite and space-vehicle structural components. Beryllium’s nuclear properties, combined with its low...

Mineral resource of the month: mercury

The ore of mercury, cinnabar, is soft and dark red, and native mercury is one of a few metals that is liquid at room temperatures. Cinnabar from Almaden, Spain, the world’s oldest producing mercury mine, was used during Roman times, and the chemical symbol for mercury (Hg) is from "hydrargyrum," from the Greek word meaning liquid silver. Cinnabar...

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,...

Wollastonite

In 2005, NYCO Minerals and R.T. Vanderbilt mined wollastonite in the United States. Domestic production increased slightly from 2004. The plastic market accounted for 35%-40% of US sales followed by ceramics (25-30%), metallurgical applications (10%), paint (10%), friction products (10%) and miscellaneous (5%). Towards 2006, wollastonite producers...

Exploration

The worldwide budget for nonferrous, nonfuel mineral exploration was expected to increase by 58 percent in 2004 from the 2003 budget, according to Metals Economics Group (MEG) of Halifax, Nova Scotia. The increase comes two years after a five-year period of declining spending for mineral exploration (1998 to 2002). Figures suggest a subsequent 27...
