Extraction and separation of platinum, palladium and,

Despite their limited availability the demand for these metals is increasing. Therefore efficient extraction and separation procedures for PGMs are essential for the recycling of these metals from secondary sources or postconsumer scrap. The consumption of platinum and palladium by the autocatalyst sector is rising by 5% each year.Platinum group | chemical element group | Britannica,Virtually all platinum-group metals are recovered from copper or nickel sulfide minerals, which are concentrated by flotation separation. Smelting of the concentrate produces a matte that is leached of copper and nickel sulfides in an autoclave. The solid leach residue contains 15Recovery and Then Individual Separation of Platinum,,Recovery of PGMs (especially rhodium, platinum, and palladium) from different spent manufactured products (like catalytic 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 catalytic converter was primarily processed by crushing, grinding, and then treating in a hydrogen atmosphere. In,

Separation of platinum and palladium from chloride,

The separation of platinum and palladium from chloride solution by solvent extraction, using Alamine 300 as an extractant, has been studied. The effect of different parameters such as the concentration of HCl in the feed solution, NaCl concentration, extractant concentration, and platinum and palladium concentrations in the feed solution has been evaluated.separation platinum deals - MC World,Separation Platinum Magnetic - royalrajasthanonwheels.co. Magnetic separation is a mature, by magnetic separation This is particularly applicable to the gold, platinum and uranium mining industri. Separation of Palladium from Platinum, Iridium, and A Scheme for the Separation of Platinum…Platinum - Wikipedia,Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name is derived from the Spanish term platino, meaning "little silver". Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements.

Separation of Platinum from Palladium and Iridium in Iron,

The separation entails a two‐stage anion‐exchange procedure. In the first stage, Pt and Pd are separated from each other and from major matrix constituents including Fe and Ni. In the second stage, Ir is reduced with ascorbic acid and eluted from the column before Pt collection. Platinum yields for the total procedure were typically 50–70%.Journal of Chemistry - Hindawi Publishing Corporation,(iii) Developed method is efficient for quantitative separation of platinum(IV) in presence of various interfering cations and anions. (iv) The proposed extractive separation method is simple, rapid, selective reproducible, and suitable for separation and determination of platinum(IV) from associated metal ions, real samples, and synthetic,Integrated Ion Exchange and Liquid-Liquid Extraction,,Abstract A process for concentration and separation of platinum group metals (PGM) by a combination of ion exchange and liquid-liquid extraction is presented. First the PGM metals are dissolved by HC1/C11 and then passed through an isothiouronium anion exchange resin, where specific absorption occurs. The thiourea eluate from the resin is converted to the chloride complexes.
