where does graphite come from in the world
Graphite According to the United States Geological Survey (USGS), world production of natural graphite in 2016 was 1,200,000 tonnes, of which the following major exporters are: China (780,000 t), India (170,000 t), Brazil (80,000 t), Turkey (32,000 t) and North Korea (30,000 t).[9] Graphite is not mined in the United States, but U.S. production of synthetic graphite in 2010 was 134,000 t valued at $1.07 billion.[10]
Tungsten Tungsten, or wolfram,[7][8] is a chemical element with symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, from tung sten "heavy stone".[9] Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds. It was identified as a new element in 1781, and first isolated as a metal in 1783. Its important ores include wolframite and scheelite.
