摘要
对伴生有透辉石、石榴子石等弱磁性脉石矿物的广西平乐硅灰石矿进行了可选性研究。试验结果表明 ,采用单一强磁选方法可将硅灰石富矿粉的白度由 72提高到 84;采用强磁选 气流粉碎 浮选新工艺可将含碳质物的硅灰石贫矿粉的白度由 62提高到 81左右。
A separability study is conducted of Pingle Mine's grammite ore, which is associated with weakly-magnetic gangue minerals, such as mussite and garnet. The test results show that the whiteness of high-grade grammite powder can be increased from 72 to 84 by using single high-intensity magnetic separation, and the one of low-grade grammite powder containing carbonaceous materials from 62 to about 81 by using the HIMS-airflow pulverising-flotation flowsheet.
