A New Way to Find Platinum Group Metals

Scientists from the University of Adelaide have discovered a surprising way to find platinum group metals (PGMs)—through bacteria. According to the University's web site, investigations of platinum group elements from Brazil, Colombia and Tasmania revealed that specialized bacteria play a role in the formation and movement of platinum and related metals in surface environments.

Determination of platinum-group metals and gold in the ...

An ICP AES procedure is developed for the direct determination of all platinum-group metals (PGM) and Au in an extract based on the correlation between the main constituents of the analytical cycle. Concentrations interfering with the determination PGM and Au in the extract admissible for ICP AES were found. It was shown that the extraction system (a mixture of p-alkylaniline with oil …

Palladium element extraction method – Deep underground ...

Palladium was discovered in 1803, in London, by English chemist William H. Wollaston. He experimented on the residues left from platinum after dissolving it in aqua regia which is a concentrated solution of hydrochloric and nitric acids. After a series of chemical reactions, and then heating palladium cyanide, Wollaston could finally extract ...
