In the conterminous United States, the 17 western states consume 84 percent of the country's fresh water, mostly for agriculture. The acreage irrigated . This report summarizes the results of over three years of research that had the objectives of (i) supplementing existing knowledge of the aqueous geochemistry of platinum group elements (PGE) in the weathering environment, (ii) obtaining information concerning the distribution of these elements in the lateritic regoliths and the potential for supergene enrichment, and (iii) .
Discoveries in the Western United States and Canada were made at an increasing rate until the early s. especially as is the case of most Mesozoic or older deposits (for example. fig. reflecting an ongoing uncertainty as to the precise nature of the term. and the price of gold had increased markedly. \ r I UNITED STATES ENVIRONMENTAL PROTECTION AGENCY •f WASHINGTON, D.C.

With the support of the Open University and the Mineral Industry Research. The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have similar physical and chemical properties and occur together in nature.
The properties of PGE, such as high melting points, corrosion resistance, and catalytic qualities, make them indispensable to many industrial by: 4.

Nonetheless. Twenty-three additional elements were determined at an earlier stage for the corresponding whole coal sample of each low-temperature ash.
In the whole coal samples, gold ranges from a high of ppb to a sub-ppb level and platinum ranges from a high of ppb to a low of a few by: The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium and osmium.
They are currently receiving world-wide attention as an attractive exploration target because they offer the dual attraction of rare, high value precious metals as well as major industrial applications. Introduction. Deposits containing Ni, Cu and platinum-group elements (PGE) are usually associated with mafic and ultramafic rocks.
The deposits may be subdivided into two groups (Naldrett, ). (i) Ores with Ni and Cu as the principal products and where the noble metals (PGE and Au) are by: Pan S, Zhang G, Sun Y, Chakraborty P () Accumulating characteristics of platinum group elements (PGE) in urban environments, China.
