Beneficiation, Extraction and Metallurgical Processes is the second of two courses on extractive metallurgy by the author, written for university students as well as practicing engineers and metallurgists. Extractive metallurgy deals with ores as raw material and metals as finished products. Metallurgy has been transformed into a modern science as a result of developments in chemistry and chemical engineering. This series of courses is an introduction to the subject based in part on a course offered by the American Chemical Society under the title Metallurgical Chemistry. The full series includes... Metals, Ore Deposits and Minerals Beneficiation, Extraction and Metallurgical Processes Beneficiation, Extraction and Metallurgical Processes covers liberation and separation of minerals, extractive processes including pyrometallurgy, hydrometallurgy, electrometallurgy, and the theory of metallurgical processes including oxidation and reduction, hydration and hydrolysis, and the energetics and kinetics of reactions.

The predominant economic evaluation technique for a mineral project, from pre-feasibility study stage to operating mine, is the discounted cash flow (DCF) method. A DCF evaluation will include a detailed year-by-year cash flow projection spanning the life of the mineral reserves plus the DCF metrics of net present value (NPV) and internal rate of return (IRR). DCF methodology is accepted by industry, the financial community and regulatory bodies. This course examines the requirements, practice, and application of DCF methodology, as well as insights into the potential pitfalls to be found in such evaluations. Principal course topics include: Discounted Cash Flow Net Present Value (NPV) and Internal Rate of Return (IRR) Determination of Discount Rate Metal Price, Inflation, Debt and Taxes Targeting, Scoping and Ranking Optimizing Production Rate and Project Size Project Expansion Analysis Trade-Off Analysis Equivalent Annual Cost Analysis The course includes practical applications of DCF methodology, with examples, to project evaluation, mineral process selection, process optimization, project expansion, selection of equipment and comparison of alternatives. This course is designed for an audience of mining professionals and managers who require a practical understanding of economic evaluation and financial analysis methods and their application to mineral projects.

This course refers to the generic mining method of sublevel stoping. The most commonly used sublevel stoping mining methods are sublevel open stoping, long-hole open stoping or blasthole stoping, and vertical crater retreat (VCR). Variations of this method include vein (Alimak) mining, transverse stoping, Avoca and longitudinal mining. Sublevel stoping accounts for more than 60% of all underground production in North America. This is largely due to the developments of extension steels, hollow tube and special long-hole rock drills, and ITH drilling techniques requiring less development and greater production capacities. Several variations exist; however, characteristic to this method is the development from a top drill drive and removal of muck from a draw level below for a steeply dipping stope. The variations of the method are selected to suit the ground conditions and operational requirements of the mine. This course presents the features, design requirements, design guidelines and application of the different sublevel stoping methods.

Acid Rock Drainage (ARD) Prediction provides an introductory course and application reference for students, technicians, and practicing geochemists, geoscientists and other professionals who desire a solid grounding on the subject. The course provides sufficient knowledge and background to allow useful application of the presented information toward site assessment with regard to the evaluation of acid generation potential. By design, Acid Rock Drainage Prediction emphasizes the practical application of the concepts presented and limits the presentation of theory to the level required for a basic understanding of the topic. The aim of this course is to provide an overview of the concepts underlying acid rock drainage prediction and to act as a resource for practitioners to become more familiar with or reaquaint themselves with the topic. For those who require a specialized theoretical background on the topic, ARD Prediction provides an exhaustive list of technical references. The companion textbook to this course which contains some of the course text and has additional references should be read in conjunction with this course: Acid Mine Drainage, Rock Drainage and Acid Sulfate Soils, causes, assessment, prediction, prevention and remediation, edited by James A Jacobs, Jay H. Lehr, Stephen M. Testa, John Wiley & Sons, 2014. Principal topics covered by the course include: Chemistry, Mechanisms and Sources Site Assessment and Sampling Mineralogical and Geochemical Interpretation Static Laboratory Tests and Interpretation Kinetic Laboratory Tests and Interpretation Waste Material Management Case Studies in ARD Prediction Authors Chris Mills MSc P.Eng (Author) Bruce Downing MSc P.Geo (Co-Author) Dr. Andy Robertson P.Eng (Co-Author)   Duration: 33 Hours Access: 90 Days Category: Environment Level: Specialize Version Date: December 15, 2014   ​Need to train a team?

Metso, like its customers, understands the pressures imposed by rapidly changing technology, and the need to do more with less. In this new business environment, education and training programs have even greater importance in the maintenance and development of a company’s intellectual capital, arguably it’s most important asset. To address the needs of the plant operators, Metso Technology Development has developed a unique computer based training system (CBT). It focuses on generic principles aimed at equipping people with the knowledge to make safer, faster and better decisions. Flotation 2 - Unit Operations is a course for process engineers, mill operators and mineral processing students. This is the second of a suite of three courses on flotation from Metso Performance Solutions ... other titles include Flotation 1 - Fundamentals and Flotation 3 - Circuits. A partial list of topics covered by this course include Mechanical Flotation Cells, Column Flotation Cells, Conditioners, Regrind Mills, Cyclones and Auxiliary Equipment. In recent years the mineral processing industry has downsized its labor force, installed new technology with larger equipment and incorporated plant wide automation, all in an effort to improve productivity and performance while maintaining operating cost at a minimum. As a consequence of these actions the operator is now required to make more and better informed decisions. To meet the educational needs at the mill operation level Metso has developed a Computer Based Mill Operator Education Program. The full program includes a suite of mineral processing courses for mill operators and process engineers on Grinding and Flotation which have been adapted for Web presentation on Edumine. The program is presented by Edumine as online self-paced, self-learning courses. The courses include online certification as well as performance tracking and reporting. For information on the courses, contact support@edumine.com. Well trained operators mean higher profits, more throughput, safer operation, better morale, better grade and recovery and improved communication.
