The specific structure, technological characteristics and the operation principle of the spiral chute are briefly described in the paper, emphasis being laid on its practice of separating hematite, tin, tungsten, tantalum and niobium ores and other heavy minerals.

本文简要介绍了螺旋溜槽的结构特点，技术特性和选别原理。着重叙述了螺旋溜槽选别赤铁矿、锡矿、钨矿，钽铌矿和其它重矿物的选别实践。

The spiral chute has spiral segments with cubic-parabolic cross section, and during its operation neither mid-way cut-off of the concentrate nor adding of wash-water are needed.

螺旋溜槽的螺旋槽横截面曲线为立方抛物线，在分选过程中间不截取精矿，也不加冲洗水。

After contrast and analyse, it was found that wall-hung spiral chute is ascendant and oecumenical than wall-laid spiral chute.

通过对比得出了壁挂式相对嵌入式螺旋溜槽的优越性及技术经济效果。

The iron concentrate with qualified grade also could be beneficiated by tabling and spiral chute separation, but its recovery is distinctly lower than it obtained from intensive magnetic dressing.

用摇床或螺旋溜槽进行重选也能选出品位合格的铁精矿，但回收率显著低于强磁选。

This type spiral chute can also be used, with less investment and faster economic effect, to recover iron values from tailings, discarded by existing iron concentration plants.

螺旋溜槽还可用来从现有铁选厂的尾矿中回收铁，投资少，收效快。
