This book is based on the industry leading short course of the same name hosted by the GIW Industries Hydraulic Laboratory and founded by Dr. Roland Clift and Graeme Addie, who together with Dr. Ken Wilson continued its development and authored the first edition of this textbook. This fourth edition has been extensively updated by the international team of engineers and authors who inherited this legacy and continue its development to the present day. Focusing on the hydraulic design of slurry pipelines, the pumps that power them, and the interactions between pumps and systems, it retains the classroom tested balance of theoretical development and practical engineering which have made it a slurry transport classic. The topics covered are important to slurry system engineers for the optimization of new designs, as well as the operators of existing systems, who may need to calculate and plan for changing conditions from day to day.Updates to the fourth edition include:· Careful formulation of the theoretical concepts, providing greater clarity of slurry flow dynamics, including a new chapter on the principles and characterization of slurry flows.· Expansion of the 4-Component Models for settling slurry pipeline flow and pump solids effect, based on an extensive series of full-sized tests.· An expanded treatment of complex slurries, including a broader discussion of non-Newtonian fluids and their interaction with coarse particles.· A new chapter on test methods, presenting an overview of slurry system instrumentation, moderntechniques for characterizing slurry rheology, and practical advice for planning and executing a slurry test.· An overview of advances in the computational modeling of slurries, including an in-depth parametric study of slurry pump wear and operating cost.The authors highlight methods for achieving energy efficiency, which are crucial to the effective use of scarce resources, given the foundational role of slurry transport systems in the energy intensive industries of mining and dredging. Key concepts are supported with case studies and worked examples.Slurry Transport Using Centrifugal Pumps, fourth edition, is both methodical and in-depth. It is ideal as a teaching tool for classroom or self-directed learning domains, and valuable as a design guide for engineer practitioners at all experience levels.

This book proposes to provide a comprehensive understanding, historical and more recent research with a critical review of several aspects of the flyrock phenomenon along with classification of literature available. This puts flyrock in proper perspective and develop a comprehensive regime for flyrock prediction and control.

This book presents a detailed review of the mineral deposits and occurrences in the Arabian-Nubian Shield (ANS), including their distribution, mineralization styles, economic importance, and geological controls on the mineralization. The purpose of the book is to compile the results of past and recent investigations on mineral deposits and occurrences in the ANS that covering the countries of (Saudi Arabia, Yemen, Egypt, Sudan, Eritrea, and Ethiopia). In this regard, it discusses in detail the various genetic mineralization styles in the ANS including: (1) magmatic mineral deposits associated with mafic-ultramafic rocks (e.g. chromite, Ni-Cu-Co-PGE magmatic sulfides, Fe-Ti-V oxides), (2) intrusion-related (magmatic-hydrothermal) deposits associated with felsic to intermediate rocks (porphyry, epithermal Au-Ag/sulfide vein type family, skarn, granite-related pegmatite-REE deposits), (3) hydrothermal orogenic gold and volcanogenic massive sulfide (VMS) deposits, as well as (4) surficial mineral deposits (chemical-sedimentary, residual, mechanical and supergene enrichment deposits).

This book summarizes the links between the evolution of sedimentary basins of Northern Africa and Peri-Mediterranean in different tectonic settings and the distribution of georesources in those basins. Georesources include fossil energy, geothermal energy, deep aquifers, minerals and deposits. This book also provides key information for energy resources in these important areas. The book is in part a compilation of selected papers from Atlas Georesources International Congress, Hammamet, Tunisia, (AGIC 2017) which were extended after the congress in addition to other contributions from geoscientists based at some universities and companies from the region. It is organized in a set of research studies focusing on the architecture, geodynamic evolution and modeling of sedimentary basins in the Middle East, North Africa and the Mediterranean domain. Future developments in the exploration for water, energy and other georesources are very important in these regions. In this context, thisbook constitutes an important reference for a wide range of geoscientists and companies as it defines the distribution and potentialities of these resources.

This book composes the proceedings of the international conference on Geo-Spatial Technologies and Earth Resources (GTER 2022) which was co-organized by Hanoi University of Mining and Geology and the International Society for Mine Surveying (ISM) held at Hanoi city on October 13¿14, 2022.GTER 2022 is technically co-sponsored by Vietnam Mining Science and Technology Association (VMST), Vietnam Association of Geodesy, Cartography and Remote Sensing (VGCR), Vietnam National Coal-Mineral Industries Holding Corporation Limited (VINACOMIN), and the Dong Bac Corporation (NECO).GTER 2022 aims to bring together experts, researchers, engineers, and policymakers to discuss and exchange their knowledge and experiences in recent geospatial technologies, advances in mining and earth sciences.

Almost 80% of all data is generated in the real world, which generates a large volume of unstructured data. This unstructured data require complex processing methods, in contrast to organised data stored in databases. Text mining is an effective method for knowledge extraction and decision-making since it includes transforming unstructured text input into structured format. Classification, clustering, association rule mining, topic detection, and summarising are the main text mining tasks. This book examines cutting-edge text mining techniques and uses, such as customer relationship management, social network analysis, financial market forecasting, and document classification. Document classification, which incorporates programmes like phishing, malware, and spam detection, is one of the difficult challenges in text classification.The book suggests brand-new hybrid models for document categorization that work for both binary class and one-class problems, such as OCSVM-LSI, PCA-OCSVM, and LDA-CARM. The difficult task of stock market forecasting, which depends on unstructured news data, is also covered in the book. The suggested model predicts stock prices using a variety of regression approaches, including GMDH, GRNN, MLP, RPART, SVR, RF, and QRRF. The book provides insightful information on text mining's uses and how to make good decisions with it.

The book reviews past and present mine waste management processes. It estimates global water consumption by major mining resources per annum. This consumption will lead land use resources (agriculture and water) to collide with mining interests expected in the near future. With the application of novel metal extraction processes and the adoption of ecological engineering as an approach to waste and water management, a reduction in water and land consumption can be achieved. Using these methodologies would make mining more sustainable. Together with ore and metal recycling, mining methods can be brought into the 21st century.The book describes natural weathering processes and the microbiology of extreme environments, also known as mine sites. The role of microbes in weathering and remediation is emphasized, along with case studies of the enhancement of various ecological processes which curtail weathering and transform pollutants, creating ore bodies of the future.This book has been written as an extension to a contribution to the Oxford Research Encyclopedia. It adds depth and many examples from 40 years of multidisciplinary work with experts from geology, hydrogeology, geomicrobiology and algal physiology and chemistry, items too extensive for the Encyclopedia.          

This book is at the center of the UN goals of combining environment and economic development with new technologies.First, sustainability in mining is defined as a process of transformation. This is followed by an outlook on the aspects of safety, economy, environmental impact and digital transformation. The book includes a discussion of new aspects such as the problem of liability for mining damages regarding climate change in Peru. Specific technical issues in smart mining are covered as well, such as underground localization systems based on ultra-wide band radio and inertial navigation, or the use of thermal imaging for roof crack detection. In addition, the characterization of material flows, subsurface hydrogen-storage systems and the prediction of mining induced subsidence and uplift are dealt with.The Sustainable Smart Mining and Energy Yearbook is not only aimed at researchers professionals, but at all who want to get an overview of the important technical and legal topics in this field.
