摘要： 为检验新研制的磁性螺旋溜槽在微细粒钛铁矿回收方面的优越性，以规格型号均为BLL-600的磁性螺旋溜槽和常规螺旋溜槽为分选设备，对0.074～0.038 mm粒级和-0.038 mm粒级的钛铁矿进行了分选效果对比试验。结果表明：①0.074～0.038 mm粒级的物料在给矿浓度均为14%、给矿量均为5.4 L/min的情况下，常规螺旋溜槽1次粗选可获得TiO₂品位为27.03%、回收率为72.20%的钛粗精矿，磁性螺旋溜槽1次粗选可获得TiO₂品位为27.19%、回收率为86.04%的钛粗精矿；②-0.038 mm粒级的物料在给矿浓度均为10%、给矿量均为4.2 L/min的情况下，常规螺旋溜槽1次粗选可获得TiO₂品位为8.48%、回收率为42.83%的钛粗精矿，磁性螺旋溜槽1次粗选可获得TiO₂品位为8.43%、回收率为57.88%的钛粗精矿；③在相同工艺技术条件下，磁性螺旋溜槽比同规格型号的常规螺旋溜槽可以取得更高的TiO₂回收率；④在精矿TiO₂指标相当的情况下，磁性螺旋溜槽可显著提高处理能力。

Abstract: In order to test the superiority of new developed magnetic spiral chute in fine ilmenite recovery，the beneficiation experiments on ilmenite ores with particle sizes of 0.074~0.038 mm and -0.038 mm were conducted by adopting BLL-600 magnetic spiral chute and the conventional spiral chute.The results showed that: ①for ilmenite with particle sizes of 0.074~0.038 mm，14% of feeding concentration，and 5.4 L/min of feeding capacity，rough titanium concentrate with TiO₂ grade of 27.03% and recovery of 72.20% was obtained by one roughing using conventional spiral chute，while rough titanium concentrate with TiO₂ grade of 27.19% and recovery of 86.04% was achieved by one roughing using magnetic spiral chute.②For ilmenite in -0.038 mm，10% of feeding concentration，and 4.2 L/min of feeding capacity，rough titanium concentrate with TiO₂ grade of 8.48% and recovery of 42.83% was obtained by one roughing using conventional spiral chute，however rough titanium concentrate with TiO₂ grade of 8.43% and recovery of 57.88% was achieved by one roughing in magnetic spiral chute.③titanium concentrate recovery by magnetic spiral chute was significantly higher than that by conventional spiral chute under the same operating conditions.④the magnetic spiral chute significantly increased the capacity with the same titanium concentrate index.
