某磷矿为1956年有色冶金設計总院設計的国內第一个中大型的非金屬采选化工矿山企业。企业最終产品为磷灰石精矿,精矿杂質的允許含量为:CO_2不大于4％,Fe_2O_3+Al_2O_3及MnO_2含量不大于P_2O_5含量的8.5％。粒度要求—100目含量占90％。精矿水份要求不大于1％。根据該技术要求所进行的选矿試驗研究結果表明,精矿品位必須达到37～38％P_2O_5。
A phosphate rock for the 1956 non-ferrous Metallurgical Design Institute designed the first large-scale non-metallic mining chemical mining enterprises. The final product of the enterprise is apatite concentrate. The allowable content of impurities in the concentrate is as follows: the content of CO 2 is not more than 4%, and the content of Fe 2 O 3 + Al 2 O 3 and MnO 2 is not more than 8.5% of the content of P 2 O 5. Granularity requirements -100 head content accounted for 90%. Concentrate moisture requirements of not more than 1%. According to the technical requirements of the beneficiation test results show that the concentrate grade must reach 37 ~ 38% P_2O_5.
