For iron ore of native titanium fine dissemination size characteristics, flotation sorting is an effective process for recovering fine Ilmenite. At present, the main problem faced by flotation of fine-grained ilmenite is the selection and use of collectors in flotation reagents. In this paper, through a series of flotation tests on ilmenite single mineral, ilmenite ore and actual ore, as well as the detection and analysis of mineral surface contact angle, infrared spectrum and ultraviolet spectrum, different collectors were investigated for titanium minerals. The influence of flotation performance is to provide a theoretical reference for the development and application of new granules for fine-grained ilmenite flotation. In the thesis research, the effects of three representative single collectors (sodium oleate, salicyl hydroxamic acid and styrenephosphonic acid) on the flotation performance of ilmenite and its gangue minerals were investigated. On the basis of this, sodium oleate, which has strong ability to collect, is used as the main component of the combination agent, and it is combined with the salicylor Hydroxamic acid and styrenephosphonic acid with good selectivity to carry out single mineral and artificial mixing. Mine flotation test. The test results show that the combination of ilmenite collectors is superior to the use of any of them, and the ilmenite can be effectively recovered. The combined application study of collectors shows that there is a positive synergistic effect between the combination of sodium oleate and salicyl hydroxamic acid or styrenephosphonic acid. When they are combined, the ratio of sodium oleate: salicyl hydroxamic acid or styrenephosphonic acid = 4 ..1 is the best. At the same time, we also examined the strength of the collection of titanium minerals by a new group of collectors MOH, ROB and GYB, in order: GYBROBMOH. Through the flotation test of fine-grained and low-grade actual ore, the new collector GYB flotation ilmenite was used, and the small closed-circuit test obtained the excellent classification of the titanium concentrate grade 44.30% and the recovery rate of 66.30%. index. The determination of the contact angle of the mineral surface indicates that the contact angle of the mineral surface is related to the collector's collection performance and the pulp pH. The larger the contact angle of the mineral surface, the better the hydrophobic properties of the mineral and the higher the recovery rate. The combination application of the collector and the development of the new agent are beneficial to increase the contact angle of the mineral surface, improve the hydrophobic properties of the mineral, and make the mineral floatability better. The surface adsorption mechanism of ilmenite in the collector system was investigated by means of infrared spectroscopy and ultraviolet spectroscopy. The adsorption mode of the collector on the mineral surface and the adsorption amount of the drug were discussed. The results show that the combination of collectors and the application of new collectors not only increase the activity of the agent, but also have a stronger ability to capture and produce a surface which is hydrophobic and floatable on the surface of the mineral, thus showing better results. The selectivity. In GYB example test results confirmed theoretical, GYB occurs at the surface of the ilmenite strong chemisorption agent is bonded to an oxygen atom as the atom, bonded to the metal ion with the mineral surface, generating a cyclic chelate Object. At the same time, the research on the mechanism of action of other combined collectors and ilmenite also confirmed that chemisorption is the main mechanism of action.
