mining process for iridium

No known benefits for life processes in plants or animals. Sources. Iridium is found in its pure native form and in osmiridium, a natural alloy of iridium and osmium. Iridium is mined from sulfide layers in mafic igneous rocks where it is present with other platinumgroup elements. Most iridium is mined in Canada, Russia and South Africa.

The demand for noble metals is increasing, owing to their excellent chemical and physical properties. In order to meet the demand, the recovery of noble metals with high purity from diverse secondary resources, which contain small amounts of noble metals, is of immense value. In this work, the possibility of the separation of Au(III), Pd(II), Pt(IV), Rh(III), and Ir(IV) by solvent extraction ...

 · Iridium (Ir) is one of the scarcest elements on earth with a low occurrence of only parts per million in the earth's crust. Until today iridium is considered as a secondary mining metal, its mining production depends on the production rate of primary metals. As iridium is a PGM it is a coproduct in platinum (Pt) and palladium (Pd ...

The present study investigates a process for the selective production of hydrogen from the alytic decomposition of formic acid in the presence of iridium and iridium–palladium nanoparticles under various conditions. It was found that a loading of 1 wt.% of 2% palladium in the presence of 1% iridium over activated charcoal led to a 43% conversion of formic acid to hydrogen at room ...

film processing technique is followed. More recently, W. H. Sansom (3) has confirmed from considerable experience that there is "a relatively high, and rather un expected, degree of image contrast obtained when radiographing comparatively thin sec tions of steel [with iridium 1921even down to 7 Ib plate, which, with reinforcement, is approximately inch". Sansom reports that in the ...

Iridium is also obtained commercially as a byproduct from nickel and copper mining and processing. During electrorefining of copper and nickel, noble metals such as silver, gold and the platinum group metals as well as selenium and tellurium settle to the bottom of the cell as anode mud, which forms the starting point for their extraction. To separate the metals, they must first be brought ...

In processes for the recovery and separation of the platinum metals from mineral deposits it is frequently necessary to separate and purify platinum, iridium and rhodium from aqueous solutions containing salts of all three together with small quantities of dissolved base metals such as iron, copper, nickel, tin and selenium present to the extent of up to 5% by weight.

 · Iridium the Precious Metal With A Precious Investment. Iridium is one of 31 transitional metals and one of a handful of precious metals along with gold, silver, platinum and palladium.
