Theory teaching
One of the first and most basic steps in the technological treatment of geogenic and technogenic 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 - refineries of mining, processing, extractive and hydrometal waste, smelting and industrial waste, in general. Formation of the primary sample from the deposit or in the preparation plant; determination of sample representativeness and processing. The curriculum of this course envisages the use of a number of methods of testing mineral resources, such as mineralogical minerocroscopic tests, structural-texture analysis of ores, minerals release tests; determination of 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
Qualitative-quantitative mineral composition. Study of the elemental composition of minerals and mineral - geogenic or technogenic raw materials. Chemical and physico-chemical methods. Importance of Mineralogical Analysis in the Preparation of Mineral Raw Materials. Identification and characterization of minerals by stereo binocular microscope (physical properties of minerals), ore polarization microscope (optical minerals), image analyzer. Production of ore and special briquetted microscopic preparations. Rational analysis. Modal mineral analysis. Prognosis, scientific research and control mineralogical testing of products Preparation of mineral raw materials. Investigation of the shape and intensity of alterations in technical raw materials. Opening of the raw material and the level of release of minerals in the process of crushing. Defining the degree of liberation of minerals, the method of measurement, showing the results. Modeling of raw materials and models of crushing. Integral Release Rate (ISO). ISO in the function of finishing grinding raw materials. The relevance of the liberation of minerals on the selectivity of the separation of minerals. Quantitative analysis in ore microscopy. Measurement techniques: De Lesse method (planimetric), Rosiwal-Shand method (linear), Glagolev-Case method (points); Flit’s method, Van der Plas’s method of tape, Galehous line method, accuracy of analysis of raw materials and products Preparation of mineral raw materials with the help of ore microscope. Minerals release: raw material models, models of liberation; approaches; recording techniques, displaying results. An integral degree of liberation. Importance.
