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
Download or read book Beyond the crises Zimbabwe s prospects for transformation written by Murisa, Tendai and published by Weaver Press. This book was released on 2015-12-01 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past years, few African countries have been the focus of discussions and analyses generating a vast array of literature as much as Zimbabwe. The socioeconomic and political crises since the turn of the century have deeply transformed the country from the ideals of a vibrant freshly independent nation just two decades earlier. These transformations have necessitated the call for the restructuring of Zimbabwean society, polity, and economy. But this literature remains exclusively within the realm of academic thinking and theorising, with no concerted effort to move beyond this by explicitly drawing out the policy implications. Beyond the Crises: Zimbabwe's Prospects for Transformation is a welcome addition to the academic and policy literature with a much broader and all-embracing focus in terms of policy interventions. By focusing on different aspects of social and economic justice, Murisa and Chikweche go beyond initiating a broad discussion on these two key pillars of human development with a view to suggesting possible future directions of practical solutions and policy development for the attainment of inclusive social and economic justice for Zimbabweans.

Download or read book Biological Phosphate Removal from Wastewaters written by R. Ramadori and published by Elsevier. This book was released on 2017-01-31 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Phosphate Removal from Wastewaters contains the proceedings of an International Association on Water Pollution Research and Control Specialized Conference held in Rome, Italy on September 28-30, 1987. Contributors review advances that have been made in the removal of biological phosphates from wastewaters, both at the fundamental scientific level and in the practical application of the process. Topics range from the fundamental microbiology and biochemistry of the enhanced biological removal of phosphate to the practical full-scale plant experiences with phosphorus removal and sludge handling from such processes. This text is comprised of 43 chapters; the first of which describes the utilization of polyphosphate as an energy reserve in Acinetobacter sp. and activated sludge. Attention then turns to metabolic control in polyphosphate-accumulating bacteria and its role in enhancing biological phosphate removal. The biochemistry and energetics of biological phosphorus removal are also considered. The next section is devoted to process modeling and includes chapters that explore the kinetics of biological excess phosphorus removal; factors affecting anaerobic stabilization during biological phosphorus removal; and the behavior of magnesium in biological phosphate removal. In the next section, bench/pilot-scale studies are presented; one of which investigated the reduction of returned phosphorus from a sludge treatment process. The book concludes with a discussion on phosphate removal mechanisms and pilot- and full-scale experiences. This book will be of interest to students, practitioners, and policymakers in water pollution control.

Download or read book Smart Technologies for Sustainable Smallholder Agriculture written by David Chikoye and published by Academic Press. This book was released on 2017-04-07 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart Technologies for Sustainable Smallholder Agriculture: Upscaling in Developing Countries defines integrated climate smart agricultural technologies (ICSAT) as a suite of interconnected techniques and practices that enhance quantity and quality of agricultural products with minimum impact on the environment. These ICSAT are centered on three main pillars, increased production and income, adaptation and resilience to climate change, and minimizing GHG emissions. This book brings together technologies contributing to the three pillars, explains the context in which they can be scaled up, and identifies research and development gaps as areas requiring further investigation. It stresses the urgency in critically analyzing and recommending ICSAT and scaling out the efforts of both developing and disseminating these in an integrated manner. The book discusses, synthesizes, and offers alternative solutions to agriculture production systems and socio-economic development. It brings together biophysical and socioeconomic disciplines in evaluating suitable ICSAT in an effort to help reduce poverty and food insecurity. - Highlights the research gaps and opportunities on climate smart agricultural technologies and institutional arrangements - Provides information on institutional engagements that are inclusive of value chain actors that support partnerships and the development of interactive platforms - Elaborates some of the effects of climate extremes on production and socioeconomic development on small farms whose impact has potentially large impact
