C'est pourtant le troisiéme métal le plus produit dans le monde. Le 1er est le fer, puis l'Aluminium (68 millions de t en 2021) puis le Chrome (41 millions de t en 2021). Devant le cuivre (21 millions de t en 2021) puis le Zinc (13 millions de t en 2021)

The world’s production (supply) and consumption (demand) of chromium have been influenced by the global market,as demand for mineral commodities,including chromium, has increased. Chromium is traded on the world market in the form of ferrochromium, an iron-chromium alloy.
The price of ferrochromium reached historically high levels in 2008 and then declined in 2009 with a weakening world economy. During the same time period, China’s role as a chromium consumer has grown with its expanding stainless steel industry.
Ferrochromium production is an electrical energy-intensive process. Much of the electrical power currently produced is coal based, a carbon dioxide gas-producing process that is under consideration for regulation because of its impact on climate. These factors suggest that the electrical energy cost of ferrochromium production will rise in the future.
en 2006 la production mondiale était de 20 millions de tonnes par an soit la moitié de 2021
