Bài viết giới thiệu một số kết quả phân tích góp phần làm sáng tỏ dạng tồn tại của mangan trong tinh quặng ilmenit. Kết quả nghiên cứu đạt được sẽ là thông tin quan trọng cho việc định hướng xử lý loại bỏ mangan trong ilmenit nhằm thu được sản phẩm đạt yêu cầu của ngành công nghiệp tiếp theo. | Journal of Mining and Earth Sciences Vol. 62 Issue 3b 2021 103 - 110 103 Some mineral - chemical composition results of titanium ore from the red sand layer in Binh Thuan area Gam Hong Thi Nguyen 1 Bac Hoang Bui 2 Dung Kim Thi Nhu 3 1 National institute of Mining - Metallurgy Science and Technology 2 Centre for Excellence in Analysis and Experiment Hanoi University of Mining and Geology 3 Department of Mineral Processing Hanoi University of Mining and Geology ARTICLE INFO ABSTRACT Article history Binh Thuan is an area with great potential for titanium ore in the red sand Received 24th May 2021 layer. In previous studies a suitable scheme of mineral processing and Accepted 24th Jun. 2021 types of equipment had been designed for improving the quality of Available online 20th July 2021 titanium ore concentrate. However the existence of manganese in Binh Keywords Thuan ilmenite has not been clarified and therefore an effective method Binh Thuan of separating Mn from ilmenite has not yet been proposed. In this study X-ray diffraction analysis XRD and scanning electron microscopy SEM- Ilmenite EDS and Raman spectroscopy method are used to determine the Pyrophanite mineral-chemical composition of Binh Thuan ilmenite. The analytical Titan. results show that in the study area of ilmenite ore there was a certain proportion of Mn in the Binh Thuan ilmenite ore with an average of about . Manganese is found to exist as a partial isomorphic replacement between Mn2 and Fe2 ions in ilmenite mineral crystals creating an intermediate mineral ilmenite-pyrophanite with the formula Fex Mn1- x TiO3. The obtained research results contribute to the orientation in the separation process in removing Mn effectively from Ti concentration ore. Copyright 2021 Hanoi University of Mining and Geology.
