Abstract
According to characteristics of the Damiao type vanadic-titanomagnetite deposit in the Chengde area, the mineral compositions of the deposit were studied by using artificial heavy sands separation, single mineral chemical analysis, electron probe and mineral and rock identification. The results indicate that major V-bearing minerals of the Chengde vanadium-titanium magnetite ores are Titanium magnetite and magnetite and the minor minerals are ilmenite and silicate. The major Ti-bearing minerals are ilmenite and Titanium magnetite with the minor Ti-bearing minerals being rutile and sphene. According to the positive relationship of V and Ti in the Chengde vanadium-titanium magnetite ore, a representative sample was selected for V and Ti phase project identification analysis and solvent selection experiments to determine the final phase analysis procedure of V and Ti. Four V Phase analysis projects were used to determine V in magnetite, Titanium magnetite, ilmenite and silicates with total V content. Five Ti phase analysis projects were used to determine Ti in ilmenite, magnetitie, titanium magnetite, rutile and silicates with total Ti content. The proportions of the contents of V and Ti bearing minerals over the total V and Ti contents by this method were consistent with those determined by artificial heavy sand separation. 4 kinds of Ti-bearing minerals and 3 kinds of V-bearing minerals were selected for phase analysis of 110 pieces of vanadium-titanium magnetite ore samples. The results were in accord with the mineral compositions of the actual geological samples. The established method was good for V and Ti minerals quantitative separation in vanadium-titanium magnetite ore. The established joint procedure for V and Ti phase analysis was good for the simultaneous determination of contents of the V and Ti bearing minerals.关键词
