Book Description
Recovery of Values from Low-Grade and Complex Minerals The book elaborates on various physicochemical properties of minerals and technological developments to improve the recovery of metals while ensuring cost-effectiveness and minimal environmental impact. The mineral industry is undergoing significant cultural, organizational, and technological transformations to address some of the major limitations and challenges related to the environmental and productivity domains. As far as productivity is concerned, the decrease of high-grade ores has been one of the stumbling blocks toward the achievement of maximum recovery of metals while, on the other hand, the complexity of minerals therein makes it difficult to profitably extract metals using only conventional methods. This book presents eight specialized chapters that focus on the exploration of the complexity of minerals that are likely to negatively influence the recovery of values, as well as the development of adequate technologies capable of improving the process of mineral concentration and/or metal recovery from complex minerals in a sustainable manner. It reviews the various physicochemical properties of minerals that are likely to pose a challenge during the attempt to recover values using conventional methods. It also elaborates on the recent technological development that has been considered by researchers to improve the recovery of metals from gangue-dominated minerals while ensuring cost-effectiveness and minimal adverse environmental impact. Audience This book will be of interest to academic researchers from the fields of mineral processing, hydrometallurgy, geochemistry, environment, chemistry, engineering, and professionals including mining plant operators, environmental managers in the industries, government regulatory bodies officers, and environmentalists.

Book Description
Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.

Book Description
Nickel and cobalt are strategically important metals. At present the higher grade nickel bearing ores and minerals are not adequately available for mineral industries for metal recovery. Hence the lower grade complex and oxidic nickel ores are the only available resource for extraction of nickel and cobalt. However recovery of metal values from lean grade complex ores through conventional metallurgical processes is becoming a challenge for mineral industries in the techno-economical point of view. Bioprocessing of complex and lean grade mineral is a new possibility to recover metal values at ambient conditions.

Book Description
This reprint is tightly related to minerals engineering. The solution mining (heap leaching, in situ leaching, etc.) offers an environmentally friendly, low-cost, and efficient method to extract these minerals, especially copper sulfides (chalcopyrite, chalcocite, etc.), sandstone uranium, and sandstone gold deposits. After years of development, solution mining has made great progress, but it has also encountered some technical bottlenecks. To better understand the current status of low-grade minerals and mine wastes recovery, we carefully collected 13 contributions in this Special Issue, which are mainly divided into following three aspects: - Reaction mechanisms of chemical/bio-leaching-includes the leaching kinetics of copper sulfides, assisted leaching (chloride acidic leaching, iodide assisted leaching, etc.), in situ leaching of uranium and salt deposits, etc. - Process detection, characterization, and visualization-includes the detection of reaction products, visualization of fluid flow and mass transfer, pore strucutre characterization of leaching systems (ore-packed beds, etc.), microbial successions of leaching bacteria, etc. - Recovery, recycle, and reuse of mine wastes-includes cleaner leaching, disposal or production methods (dump leaching, etc.), the recovery of mine waste (waste rock, tailings, etc.), assessment of operations problems, etc.

Book Description
Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.

Book Description
The eight articles first appeared as volume 6 (no date) of Mineral processing and extractive metallurgy review. They review new methods of recovery for gold, and to some extent, silver, focus on the particular challenges of extraction from carbonaceous ores and from various sulfide-bearing ore, and the treatment of refractory gold ore, and discuss high-temperature and biological oxidation, high- temperature chlorination, and removing metals from leach liquor.

Book Description
Hydrometallurgy '94 contains the 78 papers that were presented at the international symposium organized by the Institution of Mining and Metallurgy and the Society of Chemical Industry and held in Cambridge, England, in July 1994. In the papers specific attention is paid to the concept of sustainable development and the associated ideas of cleaner technology, recycling and waste minimization that have particular relevance to the extractiona nd processing of metals and other mineral products. The papers, by authors from 30 contries, are grouped under the headings: Hydrometallurgy and Sustainable Development; Materials Production and the Environment; Fundamentals; Leaching; Bioprocessing; Gold Solution Purification; Effluent Treatment; Processes; and Recycling.
