Antimony’s leading use is as a fire retardant in safety equipment and in household goods such as mattresses. The U.S. Government has considered antimony to be a critical mineral mainly because of its use in military applications.

Explains how a set of mineral resource province maps were compiled, what sort of information went into them, how they should be interpreted, and why they are important.

Barite (barium sulfate, BaSO4) is vital to the oil and gas industry because it is a key constituent of the mud used to drill oil and gas wells. Elemental barium is an additive in optical glass, ceramic glazes, and other products.

Reliance on imported barite to supply the United States results from numerous factors, but is primarily influenced by economic conditions, which have increasingly favored imports over domestic production in recent decades.

Beryllium is a mineral commodity that is used in a variety of industries to make products that are essential for the smooth functioning of a modern society.

Cobalt is a silvery gray metal that has diverse uses due to its ferromagnetism, hardness and wear-resistance when alloyed with other metals, low thermal and electrical conductivity, high melting point, multiple valences, and color effects with silica.

Fluorine compounds are essential in numerous chemical and manufacturing processes. Fluorspar is the commercial name for fluorite (isometric CaF2), which is the only fluorine mineral that is mined on a large scale.

Gallium is a soft, silvery metallic element with an atomic number of 31 and the chemical symbol Ga. Gallium is used in a wide variety of products that have microelectronic components containing either gallium arsenide (GaAs) or gallium nitride (GaN).

Germanium and indium are used in electronics devices, flat-panel display screens, light-emitting diodes, night vision devices, optical fiber, optical lens systems, and solar power arrays.

Amounts and global distribution of major consumer, producer, and exchange stocks of selected mineral commodities.

Steelmaking and refractory applications in metallurgy use the largest amount of produced graphite; however, emerging technology uses in large-scale fuel cell, battery, and lightweight high-strength composites promise more uses.

Explains how and why an international collaboration among geoscience agencies will help the participating nations expand and diversify critical mineral supply chains.

Lithium, the lightest of all metals, is used in air treatment, batteries, ceramics, glass, metallurgy, pharmaceuticals, and polymers.

Manganese is used to make steel, where it serves as a purifying agent in iron-ore refining and as an alloy.

Data on materials are presented provide an overview of the annual quantities (measured in physical terms) required for the standard of living in the United States and to provide insights into the consumption trajectory that developing countries may follow.

Explains how USGS evaluates disruption potential, economic vulnerability, trade exposure, and overall supply risk to develop recommendations as to which mineral commodities might be included in the official list of US critical minerals.

Detailed summaries of the production, consumption, economic valuation, and use of a wide variety of non-fuel mineral commodities in the US through 2020. Includes notes on production and resources worldwide and issues affecting the commodities both within and outside the US.

Niobium and tantalum are found together in nature because they have similar physical and chemical properties. Niobium is used in high-strength steel alloys, while tantalum is used in electronic capacitors.

The platinum-group elements (PGEs)—platinum, palladium, rhodium, ruthenium, iridium, and osmium—are metals that have similar physical and chemical properties and tend to occur together in nature. PGEs are indispensable to many industrial applications.

Because of their unusual physical and chemical properties, the REEs have diverse defense, energy, industrial, and military technology applications including glass, petroleum refining, automobiles, and magnets.

Rhenium is a rare metal that has an extremely high melting point and a heat-stable crystalline structure. It is used in high-temperature superalloys, to make turbine blades for jet aircraft engines and is a catalyst for petroleum refining.

Selenium is a trace element in Earth's crust. Modern uses for selenium include energy-efficient windows that limit heat transfer and thin-film photovoltaic cells that convert solar energy into electricity.

Tellurium is a rare element obtained as a byproduct of mining for other commodities whose main uses are in photovoltaic solar cells and as an additive to copper, lead, and steel alloys in various types of machinery.

Tin (Sn) is one of the first metals to be used by humans. Almost without exception, tin is used as an alloy. Its major uses today are for cans and containers, construction materials, transportation materials, and solder.

Titanium colors paint, paper, plastic, rubber, and wallboard. Because of its strength and corrosion resistance, titanium metal and its alloys are used in the aerospace industry as well as for welding rod coatings, biological implants, and consumer goods.

Statistics for over 88 nonfuel mineral commodities including items such as production, imports, exports, price, stocks, apparent consumption, and/or net import reliance for nonfuel mineral commodities. Data are provided in CSV format.

U.S.salient statistics and world production statistics for over 88 nonfuel mineral commodities. Salient statistics for the United States includes items such as production, imports, exports, price, stocks, apparent consumption, and/or net import reliance for nonfuel mineral commodities. Data are provide in CSV format.

Explains supply and demand for US copper. Worldwide demand increased, much of that from China. Chinese demand for copper scrap from the US has decreased recently, which could lead to an oversupply and declining prices.

Vanadium is used primarily in the production of steel alloys; as a catalyst for the chemical industry; in the making of ceramics, glasses, and pigments; and in vanadium redox-flow batteries (VRBs) for large-scale storage of electricity.

Relational database describing 102 materials from the early 1800s to circa 2017 through anthropogenic cycles, their recycling and criticality properties, and on spatial scales ranging from suburbs to global. Provided as MySQL, PostgreSQL, and CSV formats.

Zirconium and hafnium are corrosion-resistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon or as zirconium oxide or other zirconium chemicals.
