ADVANCE YOUR CAREER

If you are an exploration geologist, a mining engineer, a metallurgist, a mine accountant, or a practitioner of any of a number of other mining-related specialties, at some time you will be asked to do a cost estimate. Mining is an economic endeavor, and, after safety, the cost of mining and its related processes is one of the most important considerations in that endeavor. This course introduces you to the methodologies of mining cost estimating, and prepares you to complete a credible estimate. The course focuses on itemized cost estimating methods in the context of a mine plan. It covers the costs of excavating, loading, hauling, drilling and auxiliary equipment as well as the costs of supply, personnel, stripping and other requirements. This is a premium course which has been peer-reviewed by a committee appointed by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and the Society for Mining, Metallurgy and Exploration (SME).

The investment necessary to start a mine is of the order of 10's to 100's of millions of dollars. In order for the investment to be profitable, the potential product in the ground must be present in adequate quantities and quality to justify a decision to invest. Mining and processing systems used to extract the products must then operate so as to produce revenue to offset the planned investment and to provide an acceptable profit. Clearly, all technological and financial decisions regarding planned production are built on an understanding of the mineral assets available. Thus, the estimation of grade and location of material in the ground (in situ resources) must be known with an acceptable degree of confidence. This is especially true of certain large, low grade deposits for which grade is only slightly above minimum profitable levels, and for some precious metal deposits where only a small percentage of mineralized ground can be mined at a profit. Mining profits are strongly leveraged to product price and to realized grade of material mined. A small difference between planned (estimated) and realized production grade, or a small change in metal price, can have a large impact on mine profitability. The three undertakings, ore estimation, mine planning and grade control, are complementary in an efficient mining operation and are natural progressions one to another. The integration of these three endeavors is important because the grade control system must balance with the ore reserve as well as with the final products of the operating plant, and both estimation and grade control are influenced by planned operational procedures. If this balance is not achieved then the original investment may be in jeopardy. Reappraisals of mineral inventories can be necessary many times both prior to and during the life of a mine. Resource/reserve estimation procedures commonly are considered in two categories, empirical and geostatistical. This course is confined to the principal empirical methods of estimation.

Economic Geology 101 is a course for beginners in exploration geology, people requiring a basic understanding of ore deposits, students, and anyone who is inquisitive about mineral deposits and how these form. The course provides an overview of the three major rock types (igneous, sedimentary, and metamorphic rocks), and introduces the geologic processes that form or influence ore deposits. In this course, you will learn about ore deposits that are typical for various metals, including abundant metals (iron, manganese, titanium) as well as scarce base (nickel, copper, lead, zinc) and precious (platinum group elements, gold and silver) metals. World-renowned deposits are described and illustrated with numerous figures and photographs. This course is based on the Geological Framework for the Business of Exploration and Mining, authored by David Groves, produced by Market Motion Media.

Concentration and Purification of Leach Solutions is the third in a series of four hydrometallurgy courses by the author, written for university students as well as practicing engineers and metallurgists. The Hydrometallurgy series covers the elementary theoretical basis of solution chemistry, the engineering aspects, and the technical applications for a large variety of raw materials, e.g. metals, oxides, sulfides, phosphates, silicates, and others. It also covers the purification-concentration steps such as adsorption on activated charcoal, ion exchange, and solvent extraction. Finally, the general aspects of precipitation from aqueous solutions are covered with numerous examples. The series is characterized by clear and simplified flowsheets, numerous chemical equations written mainly in ionic form, many illustrations for equipment and plants, and finally a lucid style presenting the facts point by point as concisely as possible. Hydrometallurgy 3 - Concentration and Purification of Leach Solutions covers the processes of activated charcoal adsorption, ion exchange and solvent extraction and how they relate to the concentration and purification of leach solutions.

Hydrometallurgy 1 - Introduction to Leaching covers solution chemistry, leaching mechanisms and processes, leaching methods and equipment, engineering aspects and microorganisms. Solution chemistry introduces the structure of minerals and water, elementary concepts of acids and bases, oxidation and reduction, complex formation and precipitation. These concepts are included because many metallurgy students do not have this chemistry background. The rest of the course is devoted to the general aspects of leaching of ores and concentrates, the reagents used, methods and equipment, the engineering aspects, and the role of microorganisms.
