Course Objectives:
One of the main aims is to enable the student to recognize and describe the basics types of ores and types of waste - secondary raw materials, mining waste (exploitation, processing, separation, concentration, use, etc.), to examine them and analyze reactions and processes which are inevitable in technological treatment, as well as those that engulf the environment and can be caused by mining activity. The aim of the course is to introduce students to the physical, chemical, biological, technological characteristics of mineral raw materials and waste materials. That students develop the ability to analyze and perceive the possibilities of the treatment and use system, the complex valorization of materials - ore, tailings, various technical raw materials and give them a new value. Upon completion of this course, the student is able to perform the characterization of each geogenic and technical raw material, to determine the possible directions of treatment, and to know which effects can be achieved. |
Content:
Theory teaching
One of the first and most basic steps in the technological treatment of geogenic and technogenic mineral raw materials is the characterization of materials and the estimation of the possibility of obtaining suitable useful components by different methods. Physical properties of minerals. Characteristics of geogenic or technogenic mineral raw materials - tailings of mining, processing, waste of extractive metallurgy, hydrometallurgy, smelting and industrial waste, in general. Formation of the primary sample from the deposit or preparation plant; determination of sample representativeness and processing. The curriculum of this course envisages the use of a number of methods for testing mineral resources, such as mineralogical minerocroscopic tests, structural-texture analysis of ores, minerals release tests; determination of the granulometric composition. Possibilities of fractionation of raw materials based on differences in density, electrical conductivity, magnetic properties, etc. Methods for determining the degree of release of minerals. Possibilities of release of minerals in the process of grinding of raw materials depending on the structure, composition, association, methods of aging, physical properties of minerals, oxidation, etc. Practical teaching
