Redstone shortage of gold reserves, less placer, primary ore more, especially rutile disseminated fine grain size, sorting difficult, especially difficult re-election tailing. The research on flotation and flotation collectors is the key to solving the utilization of rutile resources in China. In this paper, we have found an effective titanium- containing mineral flotation collector, TBC. From the perspectives of molecular dynamics simulation, coordination chemistry, flotation solution chemistry, and spectroscopy, the mechanism of action of collectors on minerals, especially the new agent TBC and rutile minerals was discussed. The main contents and results are as follows: Tests show that: TBC has stronger collection performance and high selectivity. Under the optimal flotation conditions, the flotation recovery rate of rutile single mineral can reach 97.5%; the rutile grade in rutile and quartz mixed ore flotation concentrate is 80%, the recovery rate is 97%; the rutile and calcite mixed ore flotation The grade and recovery rate of rutile in the concentrate are both 80%. Iron ore flotation titanium and titanium pyroxene Minerals, TBC collector also has a strong capacity and selectivity. When the pH=7 and the amount of TBC were 8×10-5mol/L, the recoveries of the two minerals were 91% and 47%, respectively. The floatability of the two minerals was significantly different at pH=5-9. The TBC is used as a collector flotation to enrich the rutile in the copper tail of Dexing and has achieved certain effects. When the grade of titanium dioxide is 11.18%, the selected grade and recovery rate of Panzhihua ilmenite mixed with TBC and oleic acid can reach 42.78% and 56.95%. As a new type of rutile collector, TBC can provide technical reference for flotation of titanium-containing minerals. The results of quantum chemical calculations illustrate the ability of TBC to capture titanium minerals from the perspective of a hard base, while the properties of Ti(IV) and Ca(II) ions can influence the choice of TBC for flotation of rutile and calcite. Sex. The calculation of molecular dynamics simulation and adsorption energy shows that the effect of TBC and rutile is stronger than that of quartz, thus achieving the selectivity to rutile flotation. Binding molecular modeling, and spectroscopic analysis of the solution chemistry can be inferred detection mechanism rutile TBC surface: in the floating mineral slurry, TBC may first close to the undissociated form of rutile and surface physical adsorption occurs, then continue to close with rutile The Ti sites on the surface are chemically bonded to form a five-membered ring-stabilized chelate, which has a strong selective collection ability.
