ADMIXTURE ELEMENTS IN IRON ORE OOLITES OF THE BAKCHAR CLUSTER (TOMSK REGION)
Geological and technological assessment of iron ore by hydraulic borehole mining is being conducted within the Bakchar iron ore cluster. The paper is focused on the admixture elements in ore oolites. To achieve the objectives, the following analytical study methods were used: X-ray fl uorescence microscopy, electron microscopy, inductively coupled plasma mass spectrometry. Based on the investigation results the contents of dopant impurities and detrimental impurities in ore oolites were determined. Forms of phosphorous occurrence are described. The main P content is associated with rare-earth phosphates. It is discovered that there are constant vanadium and manganese impurities with their contents up to 0.35% and 0.3%, respectively. The ore oolites have no high commercially significant contents of precious and rare metals.
Key words: the Bakchar iron ore cluster, oolitic ore, rare-earth phosphate, X-ray fluorescence microscopy, electron microscopy, XD analysis, inductively coupled plasma mass spectrometry.
