Extremely hard and with the highest melting point of all the elements on the periodic table, tungsten is a vital ingredient to a wide-range of industrial and military applications, yet none of this durable metal is currently mined in the United States. According to the United States Geological Survey, more than half of the tungsten consumed in the U.S. last year was used to make the cemented tungsten-carbide, a compound typically made with equal parts tungsten and carbon....
A vital ingredient in stainless steel and superalloys, chromium is considered by the United States Geological Survey as "one of the Nation's most important strategic and critical materials." "Because there is no viable substitute for chromium in the production of stainless steel and because the United States has small chromium resources, there has been concern about domestic supply during every national military emergency since World War I," the USGS explains. Rich chromite...
Cobalt is an essential ingredient to optimizing the performance of batteries in the growing number of electric vehicles on global highways, yet essentially none of this battery metal is mined in the United States. With at least one advanced stage exploration project in Alaska looking into the potential of producing cobalt alongside its copper, America's 49th State could provide a domestic source for this critical metal. In its annual report, Mineral Commodity Summaries 2018,...
The six platinum group elements – platinum, palladium, rhodium, ruthenium, iridium, and osmium – are amongst the rarest metals on Earth. This scarcity, coupled with PGEs' uses in the automotive, petrochemical and electronics industries, has this group of metals firmly planted on the United States Geological Survey's critical minerals list. "PGEs are indispensable to many industrial applications but are mined in only a few places," USGS inked in a 2017 report on platinum gro...
Primarily associated with cans, cups and roofs, tin may not be the flashiest metal on the market, but it has been a strategic metal that has defined human progress since the onset of the Bronze Age around 5,500 years ago and is on the list of minerals critical to the security of the United States even today, according to the U.S. Geological Survey. "In a congressionally mandated U.S. Department of Defense study of strategic minerals published in 2013, tin was shown to have...
Before color televisions hit the markets in the 1960s, rare earths where a curious group of elements that had the distinction of occupying their own separate section at the bottom of the periodic table but had very few practical applications. Over the ensuing 50 years, however, this group of 15 lanthanides plus yttrium and scandium have been discovered to possess unique properties that make them key ingredients in a wide range of modern products such as terabyte hard-drives...
Graphite is among the 23 metals and minerals the U.S. Geological Survey deemed critical to "the national economy and national security of the United States" in a December report, "Critical Mineral Resources of the United States – Economic and Environmental Geology and Prospects for Future Supply." One of the reasons the USGS considers graphite critical is the growing demand of this mineral as anode material in the lithium-ion batteries that power electric vehicles and a r...
The Trump Administration's focus on securing domestic sources of critical minerals could help re-invigorate mineral exploration and mine development in Alaska. At least 15 of the 23 critical minerals identified by the U.S. Geological Survey – antimony, barite, beryllium, cobalt, fluorspar, gallium, germanium, graphite, indium, platinum group elements, rare earth elements, rhenium, tantalum, tellurium, tin and vanadium – are found across the Far North state.
