摘要: 为确保司家营地区630万t高含泥贫赤铁矿顺利通过一期选矿系统,在实验室对有代表性矿样进行了分粒级强磁预选。研究表明,13~6、6~2 mm粒级试样不能正常抛废,必须直接给入原工艺系统处理;2~0 mm粒级试样湿式强磁预选效果较好,可以抛出作业产率约50%的合格尾矿,大量高含泥尾矿的抛出,有利于生产系统和选矿指标的稳定。

Abstract: In order to make sure 6 300 000 ton high mud content lean hematite at Sijiaying area pass the one stage separation system successfully, size-fractionated high intensity magnetic preconcentration was done on representative ore sample in the laboratory. The study indicates, size fraction sample of 13~6、6~2 mm could not discarding waste normally, but put into the pre-process system to handle them directly;the effect of wet high intensity magnetic preconcentration of size fraction sample of 2~0 mm is good,which could discard the qualified tailings of operation yield 50% around,discarding of a great deal of high mud content tailings are helpful to the stability of production system and mineral processing index.
