Enrichment Process

The paper presents a study of the process of enriching the waste of titanium production (sand and slag mixture) by mechanical and magnetic separation methods in order to reduce the losses of the useful component in the technology of processing ilmenite concentrate. The composition of the initial fraction of the test mixture and fractions obtained in the process of mechanical and magnetic separation was evaluated using X-ray and X-ray spectral analyzes. The particle size of the analyzed mixture was evaluated by means of a high-resolution scanning electron microscope «S-3400N» and an optical microscope «MBS-1» from a digital camera Webbers MYscope 560MCCD. As a result of the separation of the analyzed mixture by mechanical classification, it was shown that the fraction 0.16 ‑ 0.4 mm contains a considerable proportion of sand (up to 94%) and can be completely removed from the technology without further processing. The remaining fractions in addition to titanium dioxide, iron and its oxides contain a sufficiently large fraction of silicon dioxide, which can not be separated by the screen classification method. Studies on the separation of the analyzed mixture by the magnetic separation method have shown that it is possible to separate out phases of sand and titanium dioxide without iron impurities into the nonmagnetic fraction. At the same time, virtually all iron with its trivalent oxide remains in the magnetic part, as well as a sufficiently large fraction of silica and titanium particles, fused in larger pieces of the magnetic fraction. It is shown that in the process of magnetic separation, up to 100% of Fe + Fe2O3, 20% of SiO2 and 73% of TiO2 are transferred to the magnetic fraction. At the same time, with a non-magnetic fraction, on average, up to 80% of SiO2 and 27% of TiO2 are consumed.

Ilmenite phase is complex in Shaanxi.There are mainly magnetite, limonite and ilmenite, and associated with extremely small amount of rutile. According to the occurrence iron and titanium in the ilmenite ore。Paper discussed comprehensive recycling of the ilmenite using wet low-intensity magnetic separation by stage grinding process . The results show that it obtains better mineral processing indexes。The productivity of ilmenite concentrate was 28.83%, the grade of iron in concentrate was 62.05%, the content of titanium was 13.11%, iron recovery was 61.73%, titanium recovery was 43.40%.
