本文研究了苯乙烯膦酸浮选钛铁矿时,添加煤油能够提高浮选速度、扩大浮选粒度界限、降低主捕收剂的用量、提高选择性和改善泡沫性质等良好效果;对浮选攀枝花钒钛磁铁矿的磁选—浮硫化物后的尾矿—即试料(粒度为—0.315毫米、含TiO_2为17.5—18%),除用硫酸调整pH外,在不需添加其他调整剂的情况下,经一次粗选二次精选就可获得含TiO_247.7%、收率为67%(开路试验)的高品位钛精矿。
In this paper, when the styrene phosphonic acid flotation ilmenite is studied, the addition of kerosene can increase the flotation rate, enlarge the flotation particle size limit, reduce the amount of main collector, improve the selectivity and improve the foam properties and so on. Magnetic separation of Panzhihua vanadium titanomagnetite - Tailings after the floating sulfide - ie, the sample (particle size -0.315 mm, containing TiO 2 17.5-18%), in addition to sulfuric acid to adjust the pH, without the need to add other adjustments Agent, a high quality titanium concentrate containing TiO 2 with a yield of 67% (open circuit test) can be obtained after one roughing secondary selection.
