Download or read book The Recovery of Sulphur from Waste Gypsum written by Ryneth Nkhangweleni Nengovhela and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Gypsum is produced as a waste product by various industries, e.g. the fertilizer industry, the mining industry and power stations. Gypsum waste disposal sites are responsible for the leaching of saline water into surface and underground water and create airborne dust. Gypsum waste is not only an environmental problem but has measurable economic value as well. However, all these environmental and economical concerns can be avoided should valuable/saleable by-products like sulphur and calcium carbonate be recovered from the low quality gypsum. The aim of this project was to evaluate a process for converting waste gypsum into sulphur. The process evaluated consists of the following stages: reduction of gypsum to calcium sulphide: stripping of the sulphide with CO2 gas and the production of sulphur. Thermal reduction study showed that gypsum can be reduced to CaS with activated carbon in a tube furnace operating at 1100? C. The CaS yield was 96%. The CaS formed was slurried in water. The reaction of gaseous CO2 with the CaS slurry leads to the stripping of sulphide to form H2S gas and the precipitation of CaCO3. The H2S generated was then reacted in the iron (IIII) and PIPco processes to form elemental sulphur. Sulphur with the purity between 96% and 99% was recovered from waste gypsum in this study.

Download or read book Processing and Utilization of High sulfur Coals III written by Richard Markuszewski and published by Elsevier Publishing Company. This book was released on 1990 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a collection of peer-reviewed articles providing a summary of the most recent accomplishments by many of the leaders of high-sulfur coal research and development. Improvements in coal cleaning technology by application of either physical, chemical, or biological processes, and new developments in both the froth flotation and oil agglomeration methods of cleaning are reported. Innovative electrostatic and aerodynamic methods are described for cleaning coal, and progress is noted in the development of coal desulfurization by either caustic leaching, oxidative leaching, microbial treatment, or low-temperature pyrolysis. Papers also included in this book concern the capture of sulfur oxides either during or following the combustion of coal; sorbent characterization and the effects of different factors and/or additives on sorbent utilization; the capture of sulfur oxides in various types of combustion systems, including pulverized coal, slagging, fluidized bed and magnetohydrodynamic systems. Recent technical developments are reported for sorbent injection in flue-gas ducts as a means of capturing sulfur oxides.
Download or read book Beneficiation of Phosphates written by Patrick Zhang and published by Society for Mining, Metallurgy & Exploration. This book was released on 2019-06-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation from the 2018 Beneficiation of Phosphates Conference includes insights from dozens of internationally respected experts on key breakthroughs that will shape the industry in the years ahead. Learn from the best and the brightest in the industry. The book reflects on the recent impetus for reviewed research in the recovery of rare earth elements from secondary resources. Recovery of rare earth elements from phosphate processing has been one of the important projects of the Critical Materials Institute (CMI). This compilation highlights some of the findings of the CMI phosphate project. Learn how competition in the flotation reagent market has stimulated innovative reagent development work. As a result, new reagents have been formulated and targeted at dolomite flotation, calcite flotation, more selective phosphate flotation, and even flotation in seawater. The Florida phosphate industry is seeing improvements in the processing of high dolomite reserves. Recent encouraging developments include new reagents that can float dolomite without using phosphoric acid as a phosphate depressant, reducing MgO content in the “Crago” flotation concentrate thus allowing blending of some high-dolomite pebbles in the final product, and innovative gravity separation. Topics include: Sustainability and the Environment Comprehensive Extraction and Smart Chemistry Flotation Fundamentals and Reagents Advances in Processing Technology and Equipment

This book was released on 2012-12-06 with total page 1295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present in a single volume an up-to-date account of the chemistry and chemical engineering which underlie the major areas of the chemical process industry. This most recent edition includes several new chapters which comprise important threads in the industry's total fabric. These new chapters cover waste minimization, safety considerations in chemical plant design and operation, emergency response planning, and statistical applications in quality control and experimental planning. Together with the chapters on chemical industry economics and wastewater treatment~ they provide a unifying base on which the reader can most effectively apply the information provided in the chapters which describe the various areas of the chemical process industries. The ninth edition of this established reference work contains the contributions of some fifty experts from industry, government, and academe. I have been humbled by the breadth and depth of their knowledge and expertise and by the willingness and enthusiasm with which they shared their knowledge and insights. They have, without exception, been unstinting in their efforts to make their respective chapters as complete and informative as possible within the space available. Errors of omission, duplication, and shortcomings in organization are mine. Grateful acknowledgment is made to the editors of technical journals and publishing houses for permission to reproduce illustrations and other materials and to the many industrial concerns which contributed drawings and photographs. Comments and criticisms by readers will be welcome.
