The platinum-group metals (PGMs) are iridium, osmium, palladium, platinum, rhodium, and ruthenium. In general, PGMs exhibit high density, high electrical. The platinum group metals (PGMs) are a family of six structurally and chemically similar elements that are most valued for their wide range of.

Their chemical compounds have many platinum group metals, and rhodium is a particularly good catalyst. As the densest and hardest of the group, osmium is often alloyed with other PGMs such as platinum and iridium.

Osmium also is an excellent conductor of electricity and an effective oxidation catalyst. Common applications for osmium include fuel cells and forensic science.

Platinum group metals are just a few of the myriad applications for the platinum group metals. Future posts will offer more details about some of the important ways in which the PGMs influence our lives.

For example, did you know: Principal sources of this element are located in river sands of the Ural Mountains, in North and South America and also in the copper-nickel sulfide mining area of the Sudbury Basin region.

Platinum group metals the quantity at Sudbury is very small, the large amount of nickel ore processed makes rhodium recovery cost effective.

However it is commercially produced from nickel- copper deposits found in South Africa and Ontario, Canada. The huge volume of nickel-copper ore processed makes this platinum group metals profitable in spite of its low concentration in these ores.

The production of platinum group metals platinum group metals normally starts from residues of the production of other metals with a mixture of several of those metals. Purification typically starts with the anode residues of gold, copper, or nickel production.

These sulfide ores are found in mafic igneous rocks that is, dark igneous rocks with high iron and magnesium content. In recent years, old mines have been enlarged and a new mine has been established in this complex.

In large platinum group metals of platinum were discovered platinum group metals the Ural Mountains in Russia. Russia continues to be an important world source of PGM to this day. Significant amounts of platinum are recovered annually through recycling.

Properties of PGM - PMM

platinum group metals Infor example, 70 metric tons was recovered through recycling. This will continue to be an important part of PGM supplies in the future.

Uses Most platinum is used to produce catalytic converters in automobile exhaust systems. The goal is to limit the smog-producing chemicals that come from burning gasoline.

The crude rhodium metal product is converted to a soluble platinum group metals by treatment with chlorine and sodium chloride at high temperature, dissolved in water, precipitated with sodium nitrite, filtered, redissolved, and reprecipitated with ammonium chloride.

This final precipitate is reduced to a pure metal powder. The residue from rhodium sulfate leaching is fused with alkali nitrate salts to convert ruthenium to soluble sodium ruthenate.

After filtration, the solution of sodium ruthenate is treated with chlorine gas to distill off the ruthenium as the volatile compound ruthenium tetroxide. The ruthenium-bearing distillate is then treated with reducing agents to precipitate the ruthenium as a platinum group metals metal powder.

Osmium is recovered in a similar fashion, although, unlike ruthenium, it can also be recovered by distillation from acidic solutions.

The final residue is treated with sodium peroxide to convert iridium to a form soluble in hydrochloric acidfrom which it can be precipitated with ammonium chloride platinum group metals calcined to metal powder.

Simultaneous solubilization Simultaneous solubilization of all platinum group metals metals can be accomplished by fusing the mineral concentrate obtained from copper and nickel sulfide ores with aluminum metal, dissolving the aluminum, and treating the residue with hydrochloric acid and chlorine.
