Available in PDF, EPUB and Kindle. Book excerpt: Due to the increasingly complex mineralogy, and lower grade of many current ore reserves, technology has, over the past decade, had to evolve rapidly to treat these materials economically in an industry which has undergone severe periods of recession. However, most of the technical innovations, such as the increasing use of solvent-extraction, ion-exchange etc., have been in the field of chemical ore processing, and, apart from the use of computers and ever larger unit process machines, there have been few major evolutionary changes in the field of physical mineral processing, where conventional crushing and grinding methods, essentially unchanged in half a century, are followed by the 'old-faithfuls'- flotation, gravity, magnetic and electrostatic methods of separation. Many of these techniques have major limitations in the treatment of 'new' ores such as complex sulphides, and the main purpose of the NATO Advanced study Institute (ASI) "Mineral Processing at a Crossroads" was to review the future of mineral processing. One of the great failings of physical methods is their inability to treat ultra-fine particles, and much research effort is required in this area. Flotation is still the most widely used and researched method for separating minerals, and is the only method which can be used to produce separate concentrates from complex sulphide ores. However, its performance on these 'modern' ores is poor, and it is in this area particularly that chemical methods will increasingly be integrated into plant circuits.

Available in PDF, EPUB and Kindle. Book excerpt: This paper was prepared: to review the accomplishments in both high-gradient magnetic separation (HGMS) and open-gradient magnetic separation (OGMS) by the Oak Ridge National Laboratory (ORNL) group during the past three years; to show, through the medium of motion pictures, the operation of the various separation methods and devices used and developed; to show qualitative results of the separation performed; and to make available, to those interested, detailed reports of the experimental procedures and the resulting data. The qualitative separation of pyritic sulfur and ash forming minerals from fine coal by high gradient magnetic separation has been demonstrated at feed rates up to one ton per hour, and in a machine that is commercially produced in sizes for feed rates up to several hundred tons per hour. The quantitative separation of pyritic sulfur and ash forming minerals from fine coal by free fall open gradient magnetic separation has been demonstrated at a laboratory scale and at 300 kg per hour in a solenoidal magnet configuration. A magnet modeling analysis has shown that an optimum magnet can be designed with practical physical constraints which can generate separating forces two to three times those of the existing solenoidal configuration and with a large processing capacity. The analytical predictions of the behavior of particles traversing these separating forces have been experimentally confirmed within 15% in existing magnets.

Download or read book Magnetic Methods for the Treatment of Minerals written by J. Svoboda and published by Elsevier Publishing Company. This book was released on 1987 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats magnetic separation from the point of view of both the engineer in the field who operates magnetic separators and the research scientist in the laboratory. It emphasizes those aspects of magnetic separation where lack of support in fundamental research is most evident. The intention is to bring the engineer and the scientist closer together, to promote the application of basic physical phenomena in engineering practice, and to gain the acceptance of the industry. The book presents a fairly broad survey of magnetic separation as applied to and practised primarily by the mineral-processing industries, although its use in other industries is reviewed briefly. It includes information on the physical principles of magnetic separation, magnetic properties of minerals and their measurement, the generation of magnetic field, theoretical and practical problems of magnetic separation, and experience gained in the design and operation of magnetic-separation systems. In detail, the book consists of six chapters dealing with the following topics: The Physical Properties of Magnetic Separation, Review of Magnetic Separation Techniques, Theory of High-gradient Magnetic Separation, Practical Aspects of Magnetic Separation, Industrial Applications of High-gradient Magnetic Separation, and The Economics of Magnetic Separation. The six appendices deal with symbols, abbreviations, values of physical constants, conversions from one unit to another, definitions of derived units, and a list of selected equipment manufacturers. There is a comprehensive bibliography (almost 600 items) and a subject index. The book should be of value to engineers and consulting metallurgists, as well as to students who want to learn more about this branch of technology. It attempts to meet the needs of the growing number of engineers, technologists, and applied physicists who are engaged in the practical exploitation of magnetic separation.

This book was released on 2007-05-08 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reflects changes that have occurred during the last two decades in theoretical understanding and practical implementation of magnetic techniques in materials treatment. Research and development needs, based on the current strategic thinking and on principles of sustainable development are outlined. Development of magnetic separators based on powerful permanent magnetic materials, construction of reliable superconducting separators, design of efficient eddy-current separators and industrial implementation of magnetic carriers and magnetic fluids are examples of innovative changes that have taken place during the last twenty years. The book reflects the current technological trends and re-positions the research, development and practice of magnetic methods of material treatment in such areas as minerals beneficiation, recycling, waste treatment and biomedical and clinical applications.

Download or read book High-gradient magnetic separation mechanism for separation of chalcopyrite from molybdenite written by Pulin Dai and published by OAE Publishing Inc.. This book was released on 2023-10-23 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Removing molybdenite from chalcopyrite by flotation has long been a challenge due to their similar floatability as sulfide minerals. However, the difference in the magnetic susceptibility of the two minerals may be employed to address this challenge. Recently, pulsating high-gradient magnetic separation (PHGMS) has been reported effective as an environmentally friendly and economical strategy for separating chalcopyrite from molybdenite, but the mechanism of their magnetic difference is unclear. The current investigation employed crystal field theory and density functional theory calculations to theoretically elucidate the magnetic properties of these two minerals, and their difference was further demonstrated by experimental investigations. Under optimized conditions in a SLon-100 cyclic PHGMS separator, a chalcopyrite concentrate assaying 31.47% Cu and 0.44% Mo at 81.93% Cu and 5.56% Mo recoveries was produced from a pure chalcopyrite-molybdenite mixture that initially contained 26.29% Cu and 5.42% Mo. After the separation process, the Cu grade decreased to 15.06%, whereas the Mo grade increased to 16.22% in the nonmagnetic product. These findings have potential implications for the separation of chalcopyrite from molybdenite using PHGMS.

Available in PDF, EPUB and Kindle. Book excerpt: This is the final report of a one-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). High-gradient magnetic separation (HGMS) is an application of superconducting magnet technology to the process of magnetic separation of solids from other solids, liquids, or gases. The production of both high magnetic fields and large field gradients using superconducting magnet technology has made it possible to separate a previously unreachable but large family of paramagnetic materials. It is possible to separate more than half of the elements in the periodic table using this method. Because HGMS is a physical separation process, no additional or mixed waste is generated. This project sought to develop a high-gradient magnetic separator using a high-temperature superconducting magnet.
