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: lead Mineral resource of the month: lead
The United States is a major producer and consumer of refined lead, representing almost one quarter of total world production and consumption. Two mines in Alaska and six in Missouri accounted for 97 percent of domestic lead production in 2002. The United States also imports enough refined lead to satisfy almost 20 percent of domestic consumption. Other major producers or consumers of...

Mineral resource of the month: fluorspar Mineral resource of the month: fluorspar
Fluorspar, this month’s featured mineral resource commodity, has been widely used in steelmaking since the introduction of basic open-hearth furnace technology in the late 19th century. Its uses have grown and changed over the last 100 years, and now fluorspar’s most important markets are fluorochemicals, aluminum refining and steel. M. Michael Miller, Fluorspar Commodity Specialist for...

Mineral resource of the month: silicon Mineral resource of the month: silicon
In the industrialized world, silicon is as ubiquitous in the objects people use every day as it is in nature. The second most abundant element in Earth’s crust and more than 25 percent of the crust by weight, silicon is one of the most useful elements to humans.

Mineral resource of the month: sulfur Mineral resource of the month: sulfur
Since domestic sulfur production peaked at nearly 11 million metric tons in 1974, the sulfur industry has undergone dramatic change. In 1974, mined sulfur produced using the Frasch hot water method provided 8 million tons of sulfur, representing 75 percent of total elemental sulfur production. (In the Frasch process, hot water is injected directly into the sulfur-containing mineral...

Mineral resource of the month: germanium Mineral resource of the month: germanium
Germanium is a hard, brittle semimetal that first came into use over a half-century ago as a semiconductor material in radar units and in the first transistor ever made. Most germanium is recovered as a byproduct of zinc smelting, but it has also been recovered at some copper smelters and from the fly ash of coal-burning industrial power plants.

Mineral resource of the month: platinum-group metals Mineral resource of the month: platinum-group metals
The precious metals commonly referred to as platinum-group metals (PGM) include iridium, osmium, palladium, platinum, rhodium and ruthenium. PGM are among the rarest of elements, and their market values — particularly for palladium, platinum and rhodium — are the highest of all precious metals.

Mineral resource of the month: perlite Mineral resource of the month: perlite
Perlite is found in most homes, workplaces and schools. Most of the white ceiling tiles in offices and classrooms are made primarily of perlite. The soil around potted plants also has small white grains of perlite. Other than in these lightweight construction products and horticultural soil mixes, perlite is used in food processing for filtration and in natural gas processing as a low...
