Sažetak
For the first time, microstructure of representative samples of phosphorite ore was studied using electron microscopic investigation as well as scanning electron microscopy for quantitative measurements. Chemical composition of the phosphate substance that cements minerals of waste ores was defined. It was determined, that ore mineral is a phosphorus-containing mineral that by its element chemical composition corresponds to fluorocarbon-hydroxyl-apatite with the following content (% wt): 45, 23 % Ca ; 15, 67 % P ; 27, 87 % O ; 3, 77 % F and 4, 05 % Si.On the basis of the results of complex studies of phosphorite ore, and complex studies of minerals with different properties subjected to magnetic separation and flotation, there was developed a scientifically substantiated and experimentally confirmed basic technological scheme for beneficiation of phosphorite ores extracted from Malokamyshevatsk deposit, Kharkiv oblast (Izium district).
