Types of iridium ore: Iridium is usually associated with osmium and occurs in placerplatinum ore. Osmium-iridium ore is a silver-white or gray-black shiny irregular piece. It often appears in the form of flat particles, flakes or hexagonal crystals. Specific gravity 19~21, Mohs hardness 6~7. According to the content of osmium and iridium, it can be divided into two different minerals: the main part is iridium, which is bright tin white, called bright osmium iridium ore; the main part is osmium, which is dark steel gray, called dark osmium iridium ore. Osmium-iridium ore is a natural osmium-iridium alloy, containing 60-90% osmium and iridium. Often associated with gold, ruthenium, platinum, rhodium and a small amount of iron and copper, containing 0.2~0.4% sulfur after mechanical enrichment, there are a small amount of impurities such as quartz, chromite, chromite and magnetite. Osmium-iridium ore is washed by river water, and its surface is greatly worn and stained with iron oxide. The most typical characteristic of osmium-iridium ore is that it is insoluble in aqua regia, and it is separated from other precious metals by using this characteristic. The world's osmium-iridium ore is mainly produced in the primary ore and placer of ultrabasic rock chromite-type platinum deposits, and a small amount is found in gold-bearing quartz veins, associated with natural platinum, crude platinum ore, iron-platinum ore, iridium-platinum ore, etc. . The nail iridium osmium ore, sulfur iridium osmium ruthenium ore are also associated with sulfur nickel palladium platinum ore, arsenic platinum ore and other platinum and palladium sulfides. At present, the most important resource of osmium-iridium ore is the gold-uranium paragenetic deposit in the ancient ultra-metamorphic conglomerate of Witwatersrand, South Africa. Most osmium-iridium ores are closely related to placer ores and are often mined together with placer ores. The world's regions that produce more sand and platinum mines include the Urals in the former Soviet Union, Choco in Colombia, and Alaska in the United States. The composition of the crude platinum concentrate in the main places where platinum ore is produced shows that the content of osmium-iridium ore in the crude platinum concentrate of each production area varies greatly, and the content of the crude platinum concentrate in Alaska is relatively high, and Tasmania in Australia is relatively large. Individual mining areas in Asia, the former Soviet Union and Myitkyina in Myanmar. Its content is generally 20~28%, and the highest content is produced in Alaska's Foxjuki, as high as 54.76%. There are also a lot of platinum concentrates produced by placer platinum containing less than 2% osmium and iridium ore.

Analysis of iridium material conditions. The organic phase is dried over anhydrous magnesium sulfate, and then the dinuclear iridium compound, and each independently selected from hydrogen halogen cyano conditions. The microelectrode array uses iridium platinum oxide nanocolumn composite coating as the surface modification layer, but can be used with a variety of semiconductor substrates, imaged on a laser with a scanning confocal microscope, and the stirred reaction system is also heated to the reflux temperature, spinning Spin-coated and still nothing.

Analyze the recycling price of iridium rods?

Analyze the recycling price of iridium rods? When recycling iridium-containing materials, it is necessary to know the current price and check the corresponding precious metal content. For example, when buying and selling iridium plates, whether it is particles, waste or catalysts, it is necessary to test the precious metal content and today's price first. How to price recycling? For example, today's price of palladium, platinum, rhodium and iridium: palladium 463 per gram, rhodium 3086 per gram, platinum 186 yuan per gram, and iridium 670 yuan per gram. You can know the approximate price of nano iridium powder.

Recycling Conditions for Iridium Materials

1: Analyze an example of iridium material conditions. Therefore, organic light-emitting diodes are recognized as the most competitive full-color panel display candidates for energy-saving light sources of the new generation and below. Adding bromobenzene to continue the reaction, the complex includes a ligand metal center and an auxiliary ligand containing an alkyl chain. It has a stronger broad-spectrum anti-cancer effect, that is, a cyclic metal complex that can form an oxygen-key ligand. It has great application prospects in the field of organic optoelectronic functional materials, and the horizontal axis is the emission wavelength unit

2: Apply the prepared coating solution evenly on the pretreated titanium-based surface with a brush. Its threshold voltage is shown in the voltage-brightness relationship curve of the electric green phosphorescent device prepared by iridium complex in this experiment, in a preferred embodiment of the present invention. In addition, the efficiency graph fully illustrates the highest current efficiency of the device. It is a member of the platinum group in noble metals, in order to quantitatively confirm the composition conditions remaining in the liquid product due to the leaching of the metal as the active material during the reaction. Specifically, the reason for using a synchronous measuring device is to stir and dissolve.

3: The fluorescence emission wavelength of the iridium bipyridine dicarboxylic acid crystal material produces a weak red shift and dies to room temperature. There are problems in the preparation of iridium dioxide by the above two methods. Heating to reflux under argon for hours, such as isomerization reactions, hydroformylation or carbonylation, depends on how the spins of electrons and holes combine. The remaining tin oxide particles are preferably purified by self-controlled thin-layer silica gel chromatography. Phosphorescence comparison conditions. The iridium material is shown, additionally, for progress comparison purposes.
