Palladium is a critical raw material that is considered economically and strategically important by various national governments. The palladium supply chain is subject to several supply chain risks, including the geopolitical risk of potential Russian palladium export restrictions. Considering these disruption risks, it is essential to gain insight...

With platinum prices declining due to a seismic demand shift and firms grappling with the high cost of labor and prolonged production-stopping labor strikes, the financial sustainability of platinum group metal (PGM) firms has come under duress since 2012. This article seeks to understand how mining firms have reshaped their strategies to ensure fi...

En France, les produits de fission (dont le ruthénium) et les actinides mineurs, déchets ultimes de haute activité provenant du combustible nucléaire usé, sont vitrifiés. Ils forment des liaisons chimiques avec les formateurs du réseau vitreux apportés par les adjuvants de vitrification. Le ruthénium, contrairement aux autres radionucléides, est tr...

Platinum group metals, such as Pd and Pt, found in three-way catalyst converters were recycled in a two-step method: hydrodynamic cavitation followed by sonoelectrochemical dissolution. High shear forces were obtained by using a convergent nozzle with a throat diameter of 0.2 mm, feeded by a plunger pump at a pressure of 60 MPa. Cavitating submerge...

AbstractCompetitive adsorption of Au(III)- Pd(II)-, and Pt(IV)-chlorido species were carried out using generation 3 diaminobutane poly(propylene) imine dendrimer micelle (G3-DM15) and palmitic acid (C15-acid) modified superparamagnetic iron oxide nanoparticles (SPIONs). The efficacy of the adsorbents in the recovery of the three metal chlorido spec...

Global economic growth has led to an increase in cement production to meet the demand of infrastructural development over the past decades. This has resulted in cement factories being the major sources of dust pollution. Dust emanating from the cements plants deposits on buildings, roadways, on road pavements and plants. The purpose of this study w...

The effective recovery of Rh(III) from mixtures also containing Pd(II) and Pt(IV) is one of the most difficult tasks in platinum group metal refining. Adding 3,3'-diaminobenzidine (DAB) to 7 and 10 M HCl aqueous solutions containing Rh(III), Pd(II), and Pt(IV) chlorido species affords the effective separation of Rh(III) from Pd(II) and Pt(IV) throu...

With the penetration of automobiles, the number of spent automobile catalysts keeps increasing. The spent catalysts contain a significant amount of platinum group metals (PGMs) as active components. Recycling of precious metals from complex mixtures of auto-catalysts, however, is of great difficulty owing to their heterogeneity and complexity. More...
