This extensive revision deals with the minerals talc, pyrophyllite, chlorite, serpentine, stilpnomelane, zussmanite, prehnite and apophyllite. The text has been completely rewritten and very much expanded to take account of the many advances that have been made in all aspects of the Earth sciences, not least mineralogy. Each chapter is headed by a brief tabulation of mineral data and ends with full references. Crystal structures are described and illustrated, followed by discussion of structural information gained from spectroscopic as well as X-ray and electron-optic methods. Chemical sections include many analyses and structural formulae, phase relations, igneous, metamorphic and sedimenta...

This book outlines the physical and chemical foundations of high-temperature processes for producing silicon, manganese and chromium ferroalloys, alloys of molybdenum, vanadium, titanium, alkaline earth and rare earth metals, niobium, zirconium, aluminum, boron, nickel, cobalt, phosphorus, selenium and tellurium, iron-carbon alloys by carbon, silicone and aluminothermic methods. The chapters introduce the industrial production technologies of these groups of ferroalloys, the characteristics of charge materials, and the technological parameters of the melting processes. A description of ferroalloy furnaces is given in detail. Topics such as waste recycling, fines agglomeration technologies, and environmental issues are considered.
This book describes and explains the methods by which three related ores and recyclables are made into high purity metals and chemicals, for materials processing. It focuses on present day processes and future developments rather than historical processes. Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts – with platinum group metals being especially important for reducing car and truck emissions. Stainl...
Powerful and inspirational challenge to the Western Church to take the systematic, symbolic and comprehensive attacks on Christians of all denominations around the world seriously.
Nickel is an internationally traded commodity and the smallest of the LME's six base metals contracts. Its unique characteristics allow a variety of commercial and industrial applications, the most important of which is undoubtedly in the production of stainless steels. Simon Clow has set out to paint an overall picture of the nickel trade; the result is a book which genuinely covers the entire industry. It describes the history and growth, defines areas of production and explains the mechanisms of demand and consumption. Above all the book is concerned with patterns of supply, with prices and with attitudes towards different pricing mechanisms.
