Recovery and Then Individual Separation of Platinum ...
· Recovery of PGMs (especially rhodium, platinum, and palladium) from different spent manufactured products (like alytic converters) is considered as an important task as they are rarely found in nature, and they possess high economic value. In this work, the honeycomb of a car alytic converter was primarily processed by crushing, grinding, and then treating in a hydrogen atmosphere.
Hydrometallurgical extraction of platinum group metals ...
The aim of this study is to investigate the economic and technical feasibility of processing platinum group metals (PGMs) and base metals (BMs) from a lowgrade ore concentrate produced in the concentrator plant at Lonmin Pic. The PGMs of particular interest are platinum, palladium, ruthenium and rhodium, while the BMs of interest are copper and nickel. The ore concentrate, as a byproduct ...
Integrated Ion Exchange and LiquidLiquid Extraction ...
· A process for concentration and separation of platinum group metals (PGM) by a combination of ion exchange and liquidliquid extraction is presented. First the PGM metals are dissolved by HC1/C1 1 and then passed through an isothiouronium anion exchange resin, where specific absorption occurs.

Extraction And Processing Of Platinum
Extraction And Processing Of Platinum. Platinum group metals contained in coppernickel and nickel ores are extracted using research has established that the highest recoveries of these metals are achieved with a combination of our brand chemistries, aero, aerofloat, aerophine and oreprep including our new aerofloat mx 500 collector.
refining of platinum group metals / priciple flow sheet
The presence of ruthenium interferes the quality of palladium, platinum, iridium solvent extraction and rhodium precipitation. The same is true for classical old fashioned more pollutive process routes based on precipitation of Pd, Pt, and Ir as their low soluble hexachloro complex compounds. Therefore in pgm refinery circuits Ru is separated as early as possible below 50 ppm.
Production of Platinum and Palladium – Two of the Rarest ...
· The process of extracting platinum from the ore deposits is very labor intensive. In order to produce one troy once () of pure platinum, about 7 to 12 tons of ore must be extracted in a span of six months. The first step in the extraction process is to crush the ore that contains platinum and submerge it in reagent mixture with water. This is called "froth flotation" that uses ore ...
