某铁矿山选厂尾矿中含铁约9．30％，具有一定的回收价值。为了实现资源的综合利用，试验对该尾矿样进行了选矿试验研究。采用螺旋溜槽进行预先富集，富集粗精矿经再磨后采用两段弱磁磁选，磁场强度为120 KA/m，开路试验可以获得品位63．74％，回收率10．09％的铁精矿。该工艺试验指标良好，使尾矿中的铁矿物得到了有效回收，为后续矿山技改提供了技术依据。

The iron contained in the tailings of a dressing plant of an iron mine is 9 .30%, which has certain recovery value .In order to utilize the resource comprehensively , beneficiation tests were carried out .The tailings was treated first by pre -concentration with spiral chute , then the rougher concentrate was reground and went to a two -stage weak magnetic separation with a magnetic inten-sity of 20 KA/m.The open circuit test could output an iron concentrate containing 63.74% TFe with a recovery of 10 .09%.The iron ore has been recovered effectively by the process , and this will provide basis for the mine's subsequent technical reform .
