Process mineralogy combines mineralogical techniques with mineral process unit operations to identify minerals, their associations and characteristics in order to... establish feasibility concepts at the early stages of geological exploration; design processing flowsheets; specify raw materials and marketable products; troubleshoot plants; and indicate new uses of minerals. Process Mineralogy 2 for Coal and Industrial Minerals is the second of two courses on process mineralogy by the author. It presents application of the basic tools of investigative and analytical mineralogy with respect to coal and industrial minerals, illustrated by numerous examples, including... coal petrology; industrial minerals: diatomite, clay and calcium carbonate; and industrial minerals: structural clay, glass, cement and advanced ceramics. Together with the companion course, Process Mineralogy 1 for Metals (which also covers the investigative and analytical tools of process mineralogy), this course provides an excellent introduction to process mineralogy for all mining disciplines.

A tenet of investment is that if the risks of an investment are high, then the investor should be compensated for assuming the risks by a high potential return from the investment. However, quite often the risks associated with an investment are not known or understood. The results vary but may include an investment evaluation that is not representative, a bad investment decision, and low returns or even losses. Inadequate technical or financial information is the main reason risks are not taken into account or are misunderstood. Unfortunately, lack of such information is a common situation in mining and other large industrial projects. No amount of investment evaluation or analysis can compensate for lack of information. If the risks are known and can be characterized in some way, methods of investment analysis can be used to provide a quantitative assessment of the risks. One goal of this course is to describe methods for risk quantification, their advantages and limitations, and to give realistic (if not real) examples of their application. Fortunately these methods are simple so that complete evaluation of an investment is (or at least should be) a simple process.

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.

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.
