This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Thorium resources are the estimated mineral reserves of thorium on Earth. Thorium is a future potential source of low-carbon energy. [1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs. [2] [3] It is present with a higher abundance than uranium in the crust of the earth. Thorium resources have not been ...

Argus was the first price-reporting agency to apply an IOSCO audit for its energy benchmarks. [ 2 ] Argus was owned by the family of its founder Jan Nasmyth and its senior staff, but in September 2016 a majority-stake was sold to the equity firm General Atlantic valuing the company at $1.4 billion.
In event of a thorium fuel cycle, Conway granite with 56 (±6) parts per million thorium could provide a major low-grade resource; a 307 sq mile (795 sq km) "main mass" in New Hampshire is estimated to contain over three million metric tons per 100 feet (30 m) of depth (i.e. 1 kg thorium in eight cubic metres of rock), of which two-thirds is ...
US 3120435, Premo Chiotti, "Regeneration of Fission-Products-Containing Magnesium-Thorium Alloys", issued Feb 4, 1964, assigned to United States Atomic Energy Commission John J. McKetta (13 November 1996). "Thorium and ThoriuM Compounds Supply-Demand Relationships" (Google Books excerpt).
Thorium has a characteristic terrestrial isotopic composition and thus a standard atomic weight can be given. Thirty-one radioisotopes have been characterized, with the most stable being 232 Th, 230 Th with a half-life of 75,380 years, 229 Th with a half-life of 7,917 years, [ 2 ] and 228 Th with a half-life of 1.92 years.
