An Introduction to Cut-off Grade Estimation examines one of the most important calculations in the mining industry. Cut-off grades are essential to determining the economic feasibility and mine life of a project. Profitability and socioeconomic impact of mining operations are influenced by the choice of cut-off grades. Cut-off grades play a key role in estimating mineral reserves that can be publicly reported. This new edition is easier to read and of greater practical interest to practitioners. The relationship between optimization of net present value, capacity constraints, and opportunity cost is explained in greater detail. A new section discusses blending strategies, which play a critical role in an increasing number of mining operations. Author Jean-Michel Rendu, an internationally recognized expert in the management, estimation, and public reporting of mineral resources, provides practical insights. As a manager in major mining companies, a consultant, and an educator, Rendu has acquired considerable experience in all aspects of mining engineering, experience that was incorporated into this publication.

An Introduction to Cut-off Grade Estimation examines one of the most important calculations in the mining industry. Cut-off grades are essential to determining the economic feasibility and mine life of a project. Increased cut-off grades can reduce political risks by ensuring higher financial returns over a shorter period of time. Conversely, lower cut-off grades may increase project life with longer economic benefits to shareowners, employees, and local communities. Cut-off grades also impact reported reserves, which are closely monitored by stock exchanges and regulatory agencies. Author Dr. Jean-Michel Rendu, an internationally recognized expert in the management, estimation, audit, and public reporting of mineral resources, provides practical insights into this critical variable. YouOCOll learn about minimum cut-off grades, as well as those for deposits containing multiple valuable minerals. Dr. Rendu explains which costs should be included in cut-off grade calculations and considerations when planning open pit, underground, and block and panel caving operations. He shows how to optimize a copper mining project by changing grind size, and demonstrates the relationship between deposit modeling, ore control, and cut-off grades.

Does the material being mined have enough value to be worth processing? Should it be processed immediately or stockpiled? And if multiple processes are available, like heap leaching and milling, which one should be used? A cut-off grade can provide the answers. An Introduction to Cut-off Grade Estimation examines one of the most important calculations in the mining industry. Cut-off grades are essential to determining the economic feasibility and mine life of a project. Increased cut-off grades can reduce political risks by ensuring higher financial returns over a shorter period of time.

An Introduction to Cut-off Grade Estimation includes dozens of charts, graphs, and mathematical formulas to explain basic concepts in a simple, step-by-step fashion. It is a "must read" for mine managers, analysts, geologists, mining engineers, and public policymakers who want to stay on the leading edge of their profession.

This SME classic is both a reference book for the working engineer and a textbook for the mining student. This hardcover edition gives a brief history of surface mining and a general overview of the state of surface mining today--topics range from production and productivity to technological developments and trends in equipment. This extremely useful text takes the approach that exploration and mining geologists must be expert in a number of fields, including basic finance and economics, logistics, and pragmatic prospecting. Readers will find material on all these topics and more. The book's nine chapters include: Introduction, Exploration and Geology Techniques, Ore Reserve Estimation, Feasibility Studies and Project Financing, Planning and Design of Surface Mines, Mine Operations, Mine Capital and Operating Costs, Management and Organization, and Case Studies. The book is fully indexed.

This comprehensive textbook covers all major topics related to the utilization of mineral resources for human activities. It begins with general concepts like definitions of mineral resources, mineral resources and humans, recycling mineral resources, distribution of minerals resources across Earth, and international standards in mining, among others. Then it turns to a classification of mineral resources, covering the main types from a geological standpoint. The exploration of mineral resources is also treated, including geophysical methods of exploration, borehole geophysical logging, geochemical methods, drilling methods, and mineral deposit models in exploration. Further, the book addresses the evaluation of mineral resources, from sampling techniques to the economic evaluation of mining projects (i.e. types and density of sampling, mean grade definition and calculation, Sichel’s estimator, evaluation methods – classical and geostatistical, economic evaluation – NPV, IRR, and PP, estimation of risk, and software for evaluating mineral resources). It subsequently describes key mineral resource exploitation methods (open pit and underground mining) and the mineral processing required to obtain saleable products (crushing, grinding, sizing, ore separation, and concentrate dewatering, also with some text devoted to tailings dams). Lastly, the book discusses the environmental impact of mining, covering all the aspects of this very important topic, from the description of diverse impacts to the environmental impact assessment (EIA), which is essential in modern mining projects.

El sector de las industrias extractivas (IE) ocupa un lugar considerable en las economías de muchos países en desarrollo. Los economistas y los profesionales de las finanzas públicas que trabajan en estos países suelen enfrentarse a problemas que exigen un entendimiento profundo del sector, su economía, su buen gobierno y los desafíos en materia de políticas, así como a las consecuencias de la abundancia de recursos naturales para la gestión fiscal y de las finanzas públicas. El objetivo del estudio de tres volúmenes denominado Essentials for Economists and Public Finance Professionals, publicado en la serie de estudios realizados por el Banco Mundial, es presentar un panorama general conciso de los temas relacionados con las IE que estos profesionales probablemente deban encarar. En el primer volumen, "The Extractive Industries Sector", se ofrece una reseña general de las cuestiones fundamentales para la economía de las IE; se analizan los componentes principales del buen gobierno, las políticas y los marcos institucionales del sector, y se identifican las obligaciones de financiamiento del sector público relacionadas con las IE. El análisis de la economía de las IE abarca la valuación de los activos subterráneos, la interpretación económica del mineral y la estructura de los mercados de la energía y los minerales. En este volumen se determinan las responsabilidades de las entidades gubernamentales correspondientes y se describen las características de los marcos jurídicos y normativos del sector de las IE. Se analizan brevemente las funciones clave y específicas del sector, además de las estructuras financieras que sustentan las salvaguardas ambientales y sociales; la inversión de los ingresos públicos provenientes del petróleo, el gas o los minerales, así como la diversificación económica basada en las industrias extractivas. Los autores esperan que este volumen resulte de utilidad a los economistas y los profesionales de las finanzas públicas que trabajan en países ricos en recursos (incluidos los encargados de la toma de decisiones en ministerios de finanzas, organizaciones internacionales y otras entidades relevantes) para la comprensión y el análisis del sector de las IE.
