The article considers the problem of improving the technology of obtaining energy-saturated materials, which results in an improvement of the characteristics of energy granules. We developed a technique for pretreatment of raw matirual in a continuous mode on a vertical vibratory mill. This contributes to the production of particles of the optimal granulometric composition.

The objective of the work is to study the aluminosilicate fractionation from fly ash, physical and mechanical properties of fly ash derived from the Thermal Power Plants (TPP) wastes. Ash, carbon concentrate (unburned carbon), ash concentrate and products of their treatment with reagents were tested by optical methods. The particle morphology of the objects of research was studied with the scanning electron microscope REM-100. The composition of the ash phases was investigated using the X-ray diffractometer DRON-2. A dispersed analysis of the TPP fly ash suggests a conclusion that it is advisable to separate particles of a narrow grain-size class within the range from 40 to 150 μm with an ash content of about 33%. The first product may be enriched by flotation method. Such a coal product may be used as a reducing medium in metallurgical processes, agglomeration, etc. The calorific capacitance of the concentrate is about 6000 kcal/kg (25000 kJ/kg).

Selected parameters of gas chromatographic analysis, which allow to determine and control the purity of industrial carotene preparations for nutrition and medicine purpose. It has been discovered that undesirable accumulation of chemical reagents in carotenoids in the course of a multi-stage and long-term biomaterial extraction mode requires additional purification from the residues of dangerous extractants.
