摘要
通过岩矿鉴定确定了某地花岗伟晶岩型黑色电气石的矿物组成结构。使用湿式强磁选方法,通过条件试验确定各项工艺参数并取得了较好的结果。电气石B2O3含量由5.38%提高至9.57%,纯度95.89%,精矿回收率可达92.84%,富集效果明显,且工艺简单可靠。
After rock--mineral analysis, the mineral composition structure of black tourmaline of granite pegmatite in a certain place is determined. Wet high intensity magnetic separation used in this research. Through the conditioning test, each process parameter is decided, and a good result is achieved. The percentage of B203 in tourmaline increases from 5.38% to 9.57%, the purity of tourmaline is 95.89%, and the percent recovery is 92.84%. The enrichment effect is obvious, and the process is simply and reliable.
