mining process for iridium
mining process for iridium,Separating the Platinum Group Metals by Liquid-Liquid Extractionseparation is concerned. An improved process which makes use of liquid-liquid extraction has been developed to a pilot plant stage, and this paper highlights some of the chemical and process principles that underlie this method of separation. The platinum group metals platinum, palladium, rhodium, iridium, osmium and.mining process for iridium,Iridium - Mining Oil and Gas JobsIridium is a chemical element found mostly alloyed with osmium and is produced as a by-product of nickel mining. South Africa, Canada and Russia are producers of iridium. Its uses are limited and are mostly used as an alloying agent and used in water pipes, gold tip pens, and medical equipment and as a treatment for.Iridium - WikipediaIridium is also obtained commercially as a by-product 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.
