| 摘 要： | 在重液分离和强磁选探索试验的基础上，按重选方案对某Cr2O3含量在14%左右的低品位铬矿石进行了多个流程的选矿试验，结果表明，将原矿磨至-0.076 mm占50%后分成+0.076 mm和-0.076 mm两个粒级进行摇床重选，可取得精矿Cr2O3品位为45.64%、Cr2O3回收率为67.99%的较好指标，从而为该低品位铬矿资源的合理开发提供了依据。

| Abstract: | Based on the exploratory experiment by the methods of separation in heavy liquid and high intensity magnetic separation,according to the gravity separation method carried out several flow-sheets to the low grade chromium ore containing Cr2O3 about 14%.The results show that after grinding the raw ore to the particle size at-0.076 mm 50%,then separating to +0.076 mm and-0.076 mm two size fraction,by gravity separation with shaking table,can get the concentrate with the grade of Cr2O3 at 45.64%,recovery at 67.99%.These provide a basis for reasonable utilization to this kind low grade chromium ore. |
