This is a list of countries by chromium ore production in 2023, based on the United States Geological Survey. [1] Chromium is a chemical element that is designated by the symbol Cr and has an atomic number of 24. It is usually found as the mineral chromite, from which ferrochrome is produced in a smelting process.

Soluble hexavalent chromium is the most common type of chromium in oceans, where over 70% of dissolved chromium in the ocean is found in oxyanions such as chromate (CrO 2− 4). Soluble trivalent chromium is also found in the oceans where complexation with organic ligands occurs. Chromium is estimated to have a residence time of
In 1986 the State of Alaska agreed to fund and take ownership of a road (DeLong Mts. Transportation System) from Red Dog to the coast, and a shallow-water port site. Also in 1986, residents of Kotzebue and 10 other area villages voted to form the Northwest Arctic Borough, to be economically based on taxing the Red Dog mine. Construction of the ...
Alaska has about 3,197 officially named natural lakes, [1] more than 409,000 natural lakes at least one hectare or bigger, [2] approximately 67 named artificial reservoirs, [3] and 167 named dams. [C] [ 4 ] For named artificial reservoirs and dams, see the List of dams and reservoirs in Alaska .
A never-before-seen ore containing vast quantities of an element widely used in semiconductors has been found in China in a discovery that could propel new advances in battery technology.
The most significant source of uvarovite historically has been a now-closed copper mine at Outokumpu, Finland, from where most museum specimens have been collected. [7] The uvarovite crystals found in the Outokumpu district are among a wide range of chromium-rich silicate phases found in association with volcanogenic copper-cobalt-zinc sulfide ore deposits which are known to have an unusually ...
