The geochemistry of chromium in the supergene environment : chromium (VI) and related speciesShaddick, Lindsay Raymond, University of Western Sydney, College of Science, Technology and Environment, School of Science, Food and Horticulture January 2003 (has links)
A description of the role of chromium in aqueous solution with respect to its geochemistry and the formation of secondary chromium minerals in the supergene environment is developed. Secondary chromium minerals are relatively rare in Nature and apart from the lead chromate crocoite which is by far the most common and also the most keenly sought after by collectors due its great beauty, little is known of related species. In attempt to redress this situation the initial aim of this study is to present an up-to-date list and description of secondary chromium minerals. It has long been recognised that secondary chromium mineralisation, in the form of chromates and compound chromates, occurs as a minor component of total secondary mineralisation in oxidised zones of some sulphide ore bodies. A thermochemical approach is adopted and a model to describe the geochemistry of chromium in aqueous solution as applied to mineral formation in the supergene environment and its transport in near surface waters is established. The model confirms that species distribution of chromium in aqueous solution is quite pH dependent and that at concentrations appropriate to those experienced in Nature, chromate is the only important species in basic solutions under highly oxidising conditions / Master of Science (Hons.)
