Abstract. As a precious platinum group element, iridium (Ir) is widely used in the fields of high-tech and military technology. The reserves of the metal iridium in Additionally, for individual mines and years where no production of ferrous ore is reported in the open database on global coal and metal mine production 12, iron An open database on global coal and metal mine production

As the raw ore grade of locally produced iron ore in China was only about 34.3% in 2018, it did not meet the requirements for iron smelting and needed to go slight increase of 0.50% year-on-year. Since 2015, China s iron ore production has gradually declined. In 2016, China s iron ore production (including low The Chinese Iron Ore Deposits and Ore Production

For decades, the steel production industry has been one of the largest sources of CO2 emissions, accounting for 7% of global CO2 emissions, of which 70% is emitted in the iron-making process. Currently, the main low-carbon iron production route is hydrogen metallurgy, which uses renewable energy to generate electricity, electrolyze Rare earths contain 17 minerals that must be separated, which is a dirty and labor-intensive effort. Today, China mines 63% of the rare earths, equating to 140,000 of the 240,000 tons globallyRare Earth Production Will Surge, But The Riches Must Be

An evaporation drying process, followed by burning with hydrogen gas, finally results in pure iridium. The global production of iridium is limited to roughly 3-4 tons per year. Most of this originates from primary ore production, although some iridium is recycled from spent catalysts and crucibles.Iridium is widely used in high-temperature corrosion protection, catalytic oxidation, and electroluminescence owing to its excellent catalytic activity, corrosion, and oxidation resistance at high temperatures. Considering the high value of iridium-containing secondary resources, scarcity of iridium, and low recovery yield, it is important to Recovery and Purification of Iridium from Secondary

Iridium is a very hard, brittle and dense metal that belongs to the platinum group. Like platinum, it is a white metal, though with a glint of yellow. It has the highest density of all the elements and a high melting point (2.454°C), and its volume mass (22,420 kg/m3) is onlyIridium Umicore

If we look at today’s technology, around 400 kg of iridium is required for every 1 GW of electrolyser capacity. To make sufficient progress towards net-zero targets, the Hydrogen Council estimates PEM capacity would need to increase to around 80 100 GW by 2030, assuming a 40% PEM market share.
