Detection of the ore component in the raw material, which is reserved in the warehouses of PJSC "Kryvbaszalizrudkom". Research subject. Determination of mass fraction of Fe (total iron) and SiO2 63 samples of raw materials of warehouses of PJSC "Kryvbaszalizrudkom" Purpose. To study the raw materials of the warehouses of PJSC "Kryvbaszalizrudkom" (63 samples) and to determine the mass fraction of Fe (total iron) and SiO2. The objectives of the research are: - development of research methods; - preparation of samples for chemical analysis according to standard research methods; - chemical study of 63 samples of raw materials of warehouses of PJSC "Kryvbaszalizrudkom"; - analysis of research results; - generalization of the received data. Research methods. Preparation of initial samples, researches of their chemical structure were carried out with use of methods of Gosstandart of Ukraine: DSTU 3195-95, 3196-95, 3198-95, 3207-95, 3210-95, and also GOST 23581.18-81 «Iron ores, concentrates, agglomerates and pellets. Method for determination of iron (total) "; GOST 23581.15-81 "Iron ores, concentrates, agglomerates and pellets. Methods for determining silicon dioxide » A research methodology was developed. Preparation of samples for chemical analysis according to standard research methods was performed. The mass fraction of Fe (total iron) and SiO2 in 63 samples of raw materials of the warehouses of PJSC "Kryvbaszalizrudkom" was determined. The results of researches are analyzed, and the received data are generalized.
