What is iridium?
Iridium is a hard, fragile, shiny and dense transition metal of platinum group . It is silvery white and is known for being the most corrosion-resistant element known. It is not affected by air, water and acid.
Among all the elements in the world, iridium is the rarest element of all elements. Although large amounts of iridium are by-products of nickel refineries, this element has been found in nature as sediments. This element is believed to have been brought to Earth by a giant meteor that contains iridium and hits Earth. It is said that many dinosaurs have been wiped out from this incident.
Iridium is not a household word, it is not surprising. After all, it was discovered in 1803. Chemists studying platinum dissolve it in a mixture of hydrochloric acid and nitric acid to produce soluble salts, and they usually produce small amounts of insoluble dark residues. A British scientist later discovered that the residue was composed of two previously undiscovered elements, osmium and iridium. The latter is named after Greek rainbow goddess Airis, because the salt obtained comes in many different colors.
It is one of the rarest stable elements in the earth's crust and the amount of gold is actually 40 times higher. When it is in a pure state, it is very fragile and nearly impossible to process. It is also one of the most corrosive metals in the world.
How much does it cost per gram of metal iridium?
How much does it cost per gram per kilogram of metal now? When recycling precious metal waste containing ruthenium platinum palladium iridium, we must refer to the current price and the corresponding precious metal content. For example, when recycling iridium powder, whether it is alloy, crucible, or plating material, you need to know its content and the latest price first. For example: iridium contains 33% in iridium powder. How to count and recover it? For example, the price of iridium is 587 yuan per gram per day. Then the value of iridium is the iridium content multiplied by weight multiplied by iridium unit price, which is its recycling price.

uses of iridium:
Currently, the demand for iridium mainly comes from the electronics industry, automobile industry and chemical industry, and is used to apply electrodes and catalysts in the chlor-alkali process. Iridium is the most corrosion-resistant material known. It is used in special alloys, forming alloys with osmium, for pen tips and compass bearings. It is used to make standard rice rods, an alloy composed of 90% platinum and 10% iridium. Due to its high melting point and low reactivity, it is also used in contacts in spark plugs in .
Iridium origin:
pure iridium may not exist in nature; its rich crust is very low, about 0.001 part per million. Although rare, iridium does exist in natural alloys with other precious metals: iridium is usually produced commercially along with other platinum metals as a by-product of nickel or copper production. Iridium-containing ore is produced in South Africa and Alaska, USA, as well as Myanmar (Myanmar), Brazil, Russia and Australia. In the late 20th century, South Africa was the main producer of iridium in the world.
