Notebaart and published by . This book was released on 1988 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large variety of ore beneficiation techniques exists. Flowsheets in operating plants range from very simple with relatively few processing steps to highly complex, involving many stages of mineral separation and extraction of valuable components by hydro- or pyrometallurgical processes. Each ore is different and requires separate flowsheet development. Although standard flowsheet types may be applied for certain ores the details should be based on the results of metallurgical testwork. During the normal course of investigations the ore is first characterised by mineralogical analysis to determine the types of ore and gangue minerals, their associations and grain sizes to estimate the required degree of comminution for liberation of the valuable minerals. Based on the results of this study possible alternative treatment methods are considered. A program of metallurgical testwork is then carried out to assess the amenability of the ore to one or more of these alternative processing routes. If the results are sufficiently promising a feasibility study is conducted, involving detailed testwork on a laboratory-scale, which may or may not be followed by piloting to generate data for a final economic analysis and plant design. In all these stages of the project, mineralogy or more generally materials characterisation, plays an important role. Metallurgical problems can often be anticipated or explained by mineralogical analysis of the feed, separation products, precipitates, leach residues, slags etc. Appropriate action can then be taken. The availability of "in house" process research facilities together with mineralogical support can result in substantial benefits to a mining company. The feedback between operations and the research group will provide an invaluable build-up of expertise. It is evident that such facilities are costly and usually only large mining companies can sustain them. The interaction between mineralogy and metallurgy forms the central theme of this thesis, which is divided into two parts. The first part commences with a general section in which the importance of mineralogy In metallurgical processing is illustrated by means of examples of applications in mineral dressing, hydrometallurgy and pyrometallurgy. Gold processing Is separately treated In view of Its current Importance. This section is followed by an overview of research work in various areas of mineral processing in relation to the central theme. The details of this research work are contained in a series of published articles which, supplemented by recent work, forms the second and main part of the thesis.

Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, software developments in Scanning Electron Microscopy (SEM) provoked a notable increase of applications to the study of solid matter. The mineral liberation analysis (MLA) of processed metal ores was an important drive for innovations that led to QEMSCAN, MLA and other software platforms. These combine the assessment of the backscattered electron (BSE) image to the directed steering of the electron beam for energy dispersive spectroscopy (EDS) to automated mineralogy. However, despite a wide distribution of SEM instruments in material research and industry, the potential of SEM automated mineralogy is still under-utilised. The characterisation of primary ores, and the optimisation of comminution, flotation, mineral concentration and metallurgical processes in the mining industry by generating quantified data, is still the major application field of SEM automated mineralogy. However, there is interesting potential beyond these classical fields of geometallurgy and metal ore fingerprinting. Slags, pottery and artefacts can be studied in an archeological context for the recognition of provenance and trade pathways; soil, and solid particles of all kinds, are objects in forensic science. SEM automated mineralogy allows new insight in the fields of process chemistry and recycling technology.

Book excerpt: Metal usage by humans is vigorously increasing day-by-day. Since the turn of the new millennium, human needs have mainly depended on different types of metal. Ores and minerals are the primary natural sources of metals. In order to process metals, manufacturers require certain methods and technology. This reference book provides six widely used varieties of metal synthesizing and the chapters are contributed by internationally reputed professors and researchers. Chapter One focuses on biomineralization. Biomineralisation is an art of nature; it is an important process where organisms produce hierarchical mineral structures with diverse functions for their survival. This process happens through the self-organisation of organic and inorganic molecules under ambient conditions, resulting in highly structured materials with remarkable physical and chemical properties. Chapter Two refers to the application of biological methods in mineral processing. Chapter Three describes monazite mineral processing; monazite is the main resource of rare earth metals such as uranium and thorium. In this chapter, monazite mining, beneficiation and metallurgical routes are discussed. Chapter Four defines the hydrometallurgy of rare earth metals, including scandium. Chapter Five deals with ore extraction technology through computer aided engineering techniques. The final chapter concludes with the processing technology used to treat primary and secondary sources for base metal recovery.

This book was released on 2022-01-31 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: b”Application of Nanotechnology in Mining ProcessesNanotechnology has revolutionized processes in many industries but its application in the mining industry has not been widely discussed. This unique book provides an overview of the successful implementation of nanotechnology in some of the key environmental and beneficiation mining processes. This book explores extensively the potential of nanotechnology to revolutionize the mining industry which has been relying for a very long on processes with limited efficiencies. The nine specialized chapters focus on applying nanoflotation to improve mineral processing, effective extraction of metals from leachates or pregnant solutions using nanoscale supramolecular hosts, and development of nano-adsorbents or nano-based strategies for the remediation or valorization of AMD. The application of nanotechnology in mining has so far received little attention from the industry and researchers and this groundbreaking book features critical issues so far under-reported in the literature: Application of nanotechnology in mineral processing for the enhancement of froth flotation Development of smart nanomaterials and application for the treatment of acid mine drainage Recovery of values from pregnant solutions using nanoadsorbents Valorization of AMD through formation of multipurpose nanoproducts. Audience Industrial interest will be from mining plant operators, environmental managers, water treatment plants managers, and operators. Researchers in nanotechnology, environmental science, mining, and metallurgy engineering will find the book valuable, as will government entities such as regulatory bodies officers and environmentalists.

Available in PDF, EPUB and Kindle. Book excerpt: Run-of-mine ore processing is a method of added value in which undesirable gangue-bearing minerals are discarded to obtain the desired minerals. Mineral processing has tangible benefits including savings in freight and handling, and the recovery of metal values from the slag as well as intangible benefits such as mineral conservation, environment protection by filling the mine using gangue-bearing minerals, and energy saving. This book provides rudimental, theoretical and operational knowledge of mineral processing along with coal characterisation and processing of ores of metallic and industrial minerals. It also explains definitions and techniques, along with basic formulas and practical examples. This book is designed for professionals in geology, mining, mineral, metallurgical and chemical engineering. The eccentric feature of this book is the introduction of simple numerical calculations for evaluation of the processes which in turn help understand the concepts with enhanced clarity and handle day-to-day operations of mineral processing plants. Therefore, it can be used both as a simple reference guide and a concise course in mineral processing.
