This book was released on 1987 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The platinum-group metals were determined in chromite materials by a fire-assay procedure in which lithium tetraborate was substituted for sodium tetraborate in the flux mixture. The results show that, while lithium tetraborate improves the dissolution of the chromite grains and is more efficient as a fluxing agent than sodium tetraborate, the values obtained for the platinum-group metals are not significantly different. Nevertheless, lithium tetraborate was found to be the preferred reagent for chromium-rich materials. Stages of the analytical procedure at which loss of the platinum-group metals may occur are identified, and recommendations are made as to how these losses can be reduced. A revised analytical laboratory method is detailed in an appendix.
Download or read book Preconcentration Techniques For Trace Elements written by Zeev Alfassi and published by CRC Press. This book was released on 1991-12-07 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate determination of trace elements is critical in various fields of science and technology. Direct measurement of trace elements in samples with complex matrices is often impractical, either due to analytical sensitivity limitations or matrix interferences. Preconcentration procedures are generally needed to eliminate matrix interferences and/or enrich minute amounts of analytes to a level for reliable measurements. Preconcentration Techniques for Trace Elements provides up-to-date information on various preconcentration techniques and detailed discussions regarding such topics as the dissolution of matrices, coprecipitation, solvent extraction, electrochemical means, ion exchange, sorption, chromatographic methods, flotation, membranes, volatization, polymer foam sorbents, fire assay, isotachophoresis, and filter papers. This comprehensive volume, featuring contributions from 21 experts from nine countries, will provide valuable reference material for all scientists and technicians dealing with trace analysis of real-world samples.

Download or read book Geo Platinum 87 written by H.M. Prichard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geo-Platinum 87 Symposium, held at the Open University during April 1987, was designed as a forum for presentation of new research results on the occurrence, genesis, geochemistry, mineralogy and analysis of the platinum-group elements (PGE). With the support of the Open University and the Mineral Industry Research Organisation, the symposium was attended by 115 representatives of university departments, research institutions and members of the mining and mineral exploration industries. An introduction to the symposium was provided by two invited papers from C. J. Morrissey (Riofinex North) and C. R. N. Clark (Johnson Matthey) which were designed to give perspective to the goals of PGE research work. The first of these papers gave a provocative insight into the aims and objectives of an exploration manager, examining the influence of supply, demand and perceived world reserves on exploration strategy. The second invited paper gave a valuable view of the industrial uses, market trends and predicted changes in the commercial value of the platinum-group elements from the standpoint of a refining company and supplier. These invited papers are reproduced in this volume and are followed by twenty four full papers and twenty abstracts that reflect the wide range of research topics presented at the symposium.

Available in PDF, EPUB and Kindle. Book excerpt: A handbook of practical techniques for professionals and students involved in the analysis of precious metals, either for exploitation or for contaminants. While most of the literature covers single techniques, it collects information on methods of analysis in a single source. After introducing the elements, basic techniques of analysis and the physical and chemical properties of precious metals are discussed. Also provides techniques for sampling for precious metals in ores, minerals, concentrates, rock, water, and biological, biogeochemical, and industrial samples.
