选别赤铁——磁铁石英岩的磁选——浮选流程的工业应用,由于强烈稀释的磁选尾矿必须预先脱水和浓缩到正常的浮选浓度,而复杂化了。这一作业或者用浓缩机,或者用水力旋流器进行。前者须要较大的浓缩面积;后者,即在水力旋流器中脱水,溢流中矿粒的粒度达10-30微米,这会造成有用矿物的大量损失 Magnetic Separation of Chiron - Magnetite Quartzite - The industrial application of the flotation process is complicated by the fact that strongly dilute magnetic separation tailings must be pre-dewatered and concentrated to a normal flotation concentration. This is done either with a thickener or with a hydrocyclone. The former requires a larger concentrate area; the latter, which is dewatered in a hydrocyclone, has a particle size of 10-30 microns in the overflow, which can result in significant loss of useful minerals
