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.
Naturally occurring tungsten consists of four stable isotopes (182 W, 183 W, 184 W, and 186 W) and one very long-lived radioisotope, 180 W. Theoretically, all five can decay into isotopes of element 72 by alpha emission, but only 180 W has been observed to do so, with a half-life of (1.8 ± 0.2) × 10 18 years; [36] [37] on average, this yields ...
Ferrotungsten is relatively expensive, with the prices around $31–44 per kilogram of contained tungsten. [4] During World War 2, over 21,000,000 lb of Ferro-tungsten and other ferroalloys were shipped to Russia on lend-lease. [3] The cost was more than $12,000,000. Ferrotungsten comes from rich ore raw materials primarily of wolframite or ...
The mine is presently active in levels 1, 2 and 3. It extracts between 700,000 and 800,000 t of ore per year and produces between 100 and 120 t of tungsten concentrates per month and other byproducts. Tin is increasing in importance as exploitation zones progresses towards mixed tungsten-tin vein zones.

President Donald Trump said Friday that a first round of tariffs on Canada, Mexico, and China will begin on his self-imposed deadline Feb. 1 but that some duties on oil and gas may be limited.
Tungsten mineral had increased in value with the outbreak of World War I and had been developed and mined by Japanese mining company (Solim Mining Corporation) until Korean independence in 1945. And in the post-Korean War decades, Sangdong mine was the powerhouse of the economy contributing more than 50% of the country's export revenue as one ...
The tin-indium-zinc North Zone contains a National Instrument 43-101-compliant resource estimate of 10,882,000 tonnes in the "indicated" category at 0.43% tin, 67.8 grams per tonne indium, and 0.67% zinc, as well as 7,603,000 tonnes in the "inferred" category at 0.22% tin, 74.6 grams per tonne indium and 0.99% zinc.
