Study On The Floatation Of Fine Rutile Ore

There was abundance of natured rutile resource in china, but it hadn't been well exploited for its low-grade, complex dissemination with other gangue minerals, fine disseminated size and illogical separation technique, our country had to import a great deal of natured rutile.It had been proved by practice that using single technique procession could not obtain satisfying result on grain rutile.At present time, most of the rutile concentrations plants had been closed down except that very few factories could maintain their production, which had rutile of coarse dissemination size.Rutile's fine dissemination size determined that single reelect was not enough and floatation was integrant, while the practice index of single floatation was not very good for lacking of reasonable procession and medicament system.After long-range research on rutile, satisfying index was obtained by unite technologic process—discarding tailing via gravity concentration and the flotation of rough concentrate. The raw concentrate's mineral composition had changed a lot to crude ore, so their regulation of floatation agents were not same. The research laid a strong emphasis on separating rutile from the higher-density silicate minerals (epidote and hornblende), and had great realism significance in rutile's exploitation and utilization.At the present time, most of the research on rutile aimed at improving technique processing of the day or analyzing adsorbent's influence on mineral's surface isolately, which was short of actual guidance on exploitation. By investigating the adsorbent mechanism of usefull mineral and gangue, the author established a new regulation of floatation agent and a new purificatory technique of rutile. Rutile was part of typical oxidation ore, and had similar structure&surface to silicate, so the research could give some ideas,and give an impulse to the separation of other oxidation ore and silicate.In the part of the basic research, electro kinetic potential of mineral's surface and infrared spectral were mensurated to lucubrate the adsorbent mechanism of rutile , epidote and hornblende. The research indicate that catenulate hornblende had less absorbability with collector and was easily to separate from Rutile by floatation, while epidote was difficult to separated from rutile for their similar surface structure which induced similar surface character. We also can separate them by changing the regulation of agent to extend the difference between rutile and epidote.
