Abstract:By means of field sampling, sample preparation, microscope observation, X-ray diffraction analysis (XRD), X-ray fluorescence spectrometry (XRF), inductively coupled plasma mass spectrometry (ICP-MS), inductively coupled plasma atomic emission spectrometry (ICP-AES), scanning electron microscopy with energy spectrum analysis and electron probe analysis, the existing state of titanium in a laterite type titanium ore of Zhijin, Guizhou Province was studied. A systematic study has been made. The results show that the content of TiO2 in the ore is between 5.02% and 8%, and the alumina-silica ratio is relatively low, so it belongs to laterite type titanium ore; titanium element exists in the mineral as an independent mineral anatase and ilmenite; titanium element replaces the iron element in hematite and occurs in hematite crystal as isomorphism; anatase can be enriched by alkali roasting and water leaching.
