Probability graphs display a data set as a cumulative distribution. The most significant use of probability graphs applied to mineral exploration data is in the recognition of the number of populations in a data set, and the partial or complete partitioning of individual values into their respective groups or populations. The significance of the resulting groupings or populations of data must be interpreted. Interpreting probability graphs is largely a matter of understanding the implications of the patterns that result when data sets are plotted. These implications are not always fully appreciated, and in some cases, the conclusions drawn from the probability graphs are incorrect. In this course, you will learn how probability graphs can supplement analyses done using histograms, and how this can be beneficial when interpreting mineral exploration data. The course explains data distributions and populations. You will learn that probability graphs are an easy way to estimate the forms of distributions and their parameters. They are a useful tool to present and analyze many types of numeric data that are the product of mineral exploration programs. The course also highlights general advantages, but also limitations of using probability graphs, and provides useful procedure tips to draw up the graphs. Note that this course assumes a working knowledge of simple statistical concepts (e.g. arithmetic mean, variance, standard deviation, normal density distribution, etc.). The course content uses a clear-cut, idealized approach illustrated by real life practical examples used throughout the mining industry. The Appendix includes a variety of interpretations of published probability graphs with alternate interpretations and discussion on the analytical approaches used by the original publications.

Practical Ore Microscopy and Mineralography is concerned particularly with information obtained from reflected light microscopy of opaque minerals. A review of the mineralographic microscope is provided at the outset, however familiarity with both the petrographic (transmitted light) and mineralographic (reflected light) microscope is a basic premise of the course. Segments of the course that follow are each more-or-less stand-alone. The course places considerable emphasis on the identification, description and classification of textures because of the enormous practical implications of ore textures to mineral beneficiation and ore genesis. Specific topics such as paragenesis, exsolution and sulfide metamorphism and sulfide phase equilibria will be of concern to those with specific interests. A variety of practical concepts related to ore microscopy (liberation, modal analysis, textural case histories, reconciling mineral proportions and assays) are discussed that pertain particularly to mineral beneficiation. Finally, a series of exercises are described that relate to information obtained from ore microscopy studies. These exercises involve topics such as: sampling of particulate ore material, changing volume percent to weight percent (and vice versa), point count and grain counting, calculating mineral formula from chemical analysis, regression as a means of determining precious metal hosts in an ore, mass balance procedures involving modal (volume) percentages of minerals and assays of metals.

Who Should Participate? People active in the design and operation of surface mines for coal and other bedded materials such as china clay, phosphate, tar sands, uranium, etc. People who prepare reclamation plans for these mines. Similarly, people who prepare permit applications and environmental impact assessments for these mines. Environmental resources and reclamation managers What You Will Learn Part 1 provides an introduction and glossary of terms. Part 2 discusses the "Nature of coal-mine overburden," including distribution of coal fields in North America, the kinds of sedimentary strata found typically above and below the coal, the connection between the depositional environment and the types of contaminants found in the overburden, and the connection between rhealogical changes when the overburden is submerged in a groundwater regime and the rock types. In Part 3 we look at "Overburden Analysis" and the kinds of tests that can be used to predict contamination and rhealogical changes. Part 4 looks at "Potential reclamation problems from routine overburden handling," which is a catalog of potential problems and is meant to reinforce the need for good planning of overburden handling. Part 5 goes over the process of "Disposal of inimical material," which is often essential to the economic success of a surface mine but can lead, if done haphazardly, to the need for almost perpetual care and treatment of discharged waters. In Part 6 we get to the heart of the course, for which the earlier materials provide the foundation, "Improved handling techniques of surface coal-mine overburden." Examples are presented and diagnosed for each of the major coal surface-mining geometries. Part 7 - Conclusions reviews the major parts of the course and suggests that individual designs, responsive to the goals of the course, may need to be tested on sophisticated mine-design software to optimize production before buying capital goods.

El curso "Molienda 2 - Operaciones unitarias" está dirigido a ingenieros de procesos, operadores de molinos y estudiantes. Este es el segundo curso de una serie de tres cursos sobre teoría y práctica de molienda de Metso Performance Solutions. Los otros dos cursos son "Molienda 1 - Principios fundamentales" y "Molienda 3 - Circuitos". Los temas abarcados incluyen: molinos de tambor, ciclones, trituradores de cono, harneros vibradores y equipos auxiliares. En años recientes, la industria de procesamiento de minerales ha reducido su fuerza laboral y ha instalado nuevas tecnologías con equipos más grandes y ha incorporado la automatización en toda la planta; todo esto en un esfuerzo para mejorar la productividad y el desempeño y minimizar los costos operativos. Como consecuencia de estas acciones, el operador debe tomar más decisiones informadas. Para satisfacer las necesidades educacionales al nivel de operación del molino, Metso Performance Solutions ha desarrollado un programa computacional de educación para el operador del molino. El programa completo incluye una serie de cursos de procesamiento de minerales para operadores del molino e ingenieros de procesos en molienda y floración, los cuales se han adaptado a cursos en línea de Edumine (detalles disponibles en Contar con operadores bien capacitados significa una mayor rentabilidad, mayor rendimiento, mayor confianza, mejor grado y recuperación y mejor comunicación.

Mobile Equipment Life Cycle Costing is a practical guide for managing the economic life of a mining truck fleet. It covers key financial, commercial and physical aspects of truck management and explains specific methods for acquiring and operating these vehicles to full advantage. The course includes three sections—Introduction, Life Cycle Cost Analysis, and Optimization. It is structured to support a vigorous discounted cash flow analysis that embraces realistic estimates for the key operating and maintenance variables associated with running haul trucks, and discusses options for improving overall truck performance and productivity. The objective is to provide an analytic framework that enables readers to impartially assess haul truck investments by using reliable financial modeling and sensitivity analysis. The life cycle model should be functional as a baseline for formal equipment planning and management and for measuring the performance of the haul truck fleet during its useful life. People who will benefit from this course include purchasing, maintenance, engineering and production managers from mining companies that operate fleets of large haul trucks.

In this course, we discuss the water and chemical mass balance of a mine site and the many components or facilities that go to make up a mine. There are as many water and chemical mass balances as there are mines. And there are as many mass balances as there are facilities on a mine. In this course we focus on the fundamental theories and methods and illustrate these with examples that are intended to assist and guide in compiling water and chemical mass balances for a mine and its various facilities. This course is one of a series of related courses, others in the series include: Groundwater in Mining Surface Water Management at Mines Objectives Reasons for undertaking a facility or site water balance study may include: evaluating strategies for optimum use of limited water supplies; establishing procedures for limiting site discharge and complying with discharge requirements; estimating the demands on water treatment plants, holding ponds, evaporation ponds, or wetlands.
