The relevance of the study is caused by the necessity to assess the possibility of associated extraction of non-ferrous, rare metals and scattered elements. The study is based on the results of analysis of samples of oolite ores from the western section of the field. In the course of research. The industrial types of iron ores of the deposit are studied, the distribution of rare metals by various industrial types, fractions of Lisakovsky iron ores and concentrates is considered The aim of the research is to study the characteristics of the ores of the Lisakovsky deposit for their complex processing. The object of research is the oolite ores of the Lisakovsky deposit. Method. Laboratory studies of ores and concentrates of the Lisakovsky deposit were carried out. Granulometric analysis by types and grades of ores was carried out. Chemical composition of ores and concentrates by fractions was studied Results. Studies of the granulometric composition of ores show that grade I and II ores consist mainly (up to 80 %) of a fraction of-0,63+0,16 mm. In grade III ore, the number of main fractions decreases to 60 %, and the number of fractions of +0,63 and-0,16 mm increases to a total of 40 %. Analysis of the results of laboratory studies of samples from the enrichment tailings shown that the content of metals: Sr, Ti, Zr, Ga, CE, Ba, Ve, Li, Cd, Y and Co, is below the standard value in the lithosphere. The content of Mn, Pb, As, W, Cr, Ni, Bi, Mo, V, Cu is higher than the average value of the metal content in the lithosphere. Thus, the contents of Cu, Ag and W exceed the clarke contents by 5, 9 and 12.5 times, and the contents of Mn, Pb and Bi are higher than the average values by 33, 55 and 59 times.
