Book excerpt: Mineral Beneficiation or ore dressing of run-of-mine ore is an upgrading process to achieve uniform quality, size and maximum tenor ore through the removal of less valuable material. Beneficiation benefits the costs of freight, handling, and extraction (smelting) reduce, and the loss of metal through slag. Usually carried out at the mine site, it s

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide a broad, comprehensive, up-to-date coverage of current beneficiation techniques and processes that are used for both metallic and nonmetallic minerals; and for other materials, such as household and industrial solid wastes, that are also processed by conventional beneficiation methods in their standard methods of recycling and reclamation. Conservation of natural resources is an adjunct of beneficiation in that we have used up once-available deposits of high-grade ores, leaving only the low-grade deposits that must be beneficiated to upgrade them to sufficiently high levels for processing and metal recovery by current extractive technology. Conservation is also important in the reclamation and recycling of indestructible, noncorrosive materials, so that they may be recovered and reused many times over. The mainly physical, relatively uncomplicated, beneficiation treatments also save large quantities of energy, as these comparatively simple operations are all relatively low energy consumers, when compared with the later separation operations of pyro and electrical nature, which are very high energy consumers. Environmentally, both air and water pollution from beneficiation treatments are either quite low or can easily be controlled, and are gas-free and operated at ambient temperature, to make them one of the cleaner and lower polluting processes used in material treatments.

Download or read book Beneficiation of Phosphates written by Zhang, Patrick and published by Society for Mining, Metallurgy, and Exploration Inc.. This book was released on 2016-06-20 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crash of the minerals super cycle is being felt by the global phosphate industry. Fortunate phosphate companies are watching their profits drop manyfold, and the not-so-lucky ones are turning to survival mode. The recent market squeeze and ever-increasing environmental pressures have, however, presented opportunities for developing technologies for extracting the most valuable elements from phosphate. This compilation from the 2015 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. Topics include: • Recovery of rare earths from phosphate • Uranium recovery from phosphoric acid • Recovery of magnesium from high-dolomite phosphate rock • Phosphoric acid purification via byproducts production

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 2013-12-16 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate). This wet process demands a phosphate rock feed that meets certain specifications to produce phosphoric acid efficiently and economically. Beneficiation of Phosphate Ore thoroughly explains the methods used in beneficiation of different types of phosphate ores for use in the wet process. The mineralogical properties of the two major types of phosphate deposits, sedimentary and igneous, are described along with the processing methods. The benefits and disadvantages of each process are discussed in detail.

This book was released on 2020-02-11 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extraction of apatite minerals is becoming more and more crucial with the depletion of high-grade ores. At the same time, many streams of waste are continuously being produced by the phosphate industry, including calcareous and siliceous waste rocks, clayey sludge and phosphogypsum. These waste products are produced in huge volumes reaching a ratio of between 5 to 10 tons of waste per each ton of concentrated phosphate. The management of these waste products is becoming a real issue in terms of growing public awareness and environmental and financial aspects. In addition, phosphate ores are known to contain other critical raw materials (CRM) such as rare earth elements and uranium. The recovery of these vital elements from phosphate waste may help to develop the needs of the green energy of the future and contribute to the achievement of the sustainable development goals. In this Special Issue, insights related to the following aspects were studied: phosphate extraction and beneficiation, novel phosphate ores, the fine characterization of phosphate ores and waste, phosphoric acid production, critical raw material (CRM) recovery from phosphate ores and waste, reprocessing of phosphate wastes and finally the valorization and reuse of phosphate waste and phosphogypsum.
