Two types of platinum group metal particles were found in borosilicate nuclear waste glasses: needle-shaped RuO2 particles and spherical PdRhxTey alloys. They form a dense sediment of high electrical conductivity and relatively high viscosity at the bottom of the ceramic melting furnace. The sludge shows a non-Newtonian flow …

Introduction. The distribution of PGEs (platinum-group elements) in an ore is directly related to the type of ore, which in turn, dictates the mineralogical constitution. PGE ores can be divided into the following main classes (Stribrny et al., 2000): Alluvial ores: These ores contain almost no sulphide and are composed of individual particles ...

This volume describes the isotopes, atoms, atomic ions, molecules, and clusters of the six platinum group elements Ru, Rh, Pd, Os, Ir, and Pt. It starts with a compilation of the properties of the isotopes, followed by the description of the formation and separation of the radioactive isotopes. The chapters on the atoms and atomic ions deal ...

Work on the electrolytic deposition of platinum and some platinum alloys is reviewed, and the results of our recent work on the deposition and the properties of the layers produced from some promising electrolytes are briefly discussed. In general, studies of plating solutions are restricted by the economic availability of the relevant platinum salts. On …

The major deposits of platinum-group elements (PGE) of the Earth are associated with ultramafic and mafic igneous rocks. ... Naldrett and Lehmann (1988) suggested that primary PGE-rich magmatic sulfide trapped within the chromitite could react with chromite to produce a Fe-rich chromite and remove sulfur from the system …

Superalloys based on platinum-group metals are being developed for hightemperature applications. These alloys have two-phase structures comprising either ordered precipitates in a matrix analogous to the nickel-based superalloys or a fine dispersion of oxide particles in a matrix analogous to oxide-dispersion-strengthened …

The ability of saline acidic oxidizing fluids (basinal brines} to transport geologically "realistic concentrations' of uranium, gold and platinum has recently been theoretically demonstrated (Jaireth, 1988). From an exploration viewpoint, the …

The Bushveld Complex in South Africa hosts the world's largest resources of platinum-group elements (PGEs), which are mainly mined from three ore bodies, namely the Merensky Reef, the UG-2 chromitite, and the Platreef. In these ores, the PGEs are bimodally distributed, occurring both as discrete platinum-group minerals (PGMs) and …

Abstract. No definite date can be ascribed to the discovery of platinum; rather it became gradually known to the Western World as a distinct metal of unique properties over a period of two centuries, between 1500 and 1700. The first source to be exploited was the placer deposits in New Granada (now Colombia) where it was initially regarded as a ...

Starting from leasing opportunities for agriculture or commercial ventures or rental properties, land offers a steady flow of revenue by transferring one's investment into a fertile cash generating property. So, it is wise to invest in lands to gain stability and possibilities for the future. Same as planting a tree and waiting to get the reward.
