Magnetic properties of rebellious ore of Guseva Gora deposit

This study continues the research implemented in the Guseva Gora deposit for some
years past. The free-milling ore sites alternate with the areas of rebellious ore although the iron content of such ore is more than 20%. In such rebellious ore areas, magnetic susceptibility was tested by downhole magnetometers in blast holes. The data of iron content from the iron content–magnetic susceptibility correlation curves often disagreed with the chemical analysis results. Furthermore, samples of ore were taken in the tested sites for laboratory examination. The magnetoacoustic emission parameters of the samples were measured, their thermomagnetic analysis was performed, and the physical properties were studied. The samples were also subjected to the mineralogical analysis. The mineralogical description of the test samples, with different shapes and sizes of grains of ore-forming minerals, showed some minor differences between them. Evidently, the determinant of the difference in the magnetic properties is not the quantity of magnetite but the form of its occurrence. Processibility of ore is governed by the degree of dispersion of magnetite (size of droplets). This parameter shows itself in the magnetic properties measured. The research findings must be used in assessment of process properties of ore.

 

Keywords: rebellious titanium–magnetite ore, magnetoacoustic emission, thermomagnetic analysis, magnetic susceptibility, domain structure, mineral composition, magnetite content and dispersiveness.
