浏阳胶磷矿的矿石特点是磷、铁、铝在各粒级中含量比较均匀,在-10微米的细泥中虽然铁铝含量较高,分布量较大,但此粒级中P_2O_5含量也达8％,而且浮选精矿中-400目的产率占40％以上,所以细粒中磷还不能丢弃,不能采用洗矿脱泥来除去铁铝。曾对磷精矿进行过磁选除铁试验,虽磁性产品中含Fe_2O_3高达14～16％,但P_2O_5含量也高达19～20％,其产率为10％,这部分产品无法利用,并使工艺流程复杂。因此,
The characteristics of ore in Liuyang plastic phosphate rock are that phosphorus, iron and aluminum content is relatively uniform in each grain size. Although the contents of iron and aluminum are higher and the distribution is larger in the fine mud of -10μm, the content of P_2O_5 Up to 8%, and flotation concentrates -400 purpose of the production rate of 40% or more, so fine particles of phosphorus can not be discarded, can not be used to wash mine desilting to remove iron and aluminum. Have conducted a magnetic separation of phosphate concentrate iron test, although the magnetic products containing Fe_2O_3 up to 14 ~ 16%, but P_2O_5 content as high as 19 to 20%, the yield was 10%, this part of the product can not be used, and Complex process. therefore,
