【摘要】 本文研究了洪雅等地铅锌矿矿石的工艺矿物学特征，根据矿石性质，试验采用粗磨—优先浮选—重选工艺流程以及多种产品的结构，成功地实现了对该资源充分合理的利用，并在生产实践中验证了该工艺技术稳妥可靠、指标好、生产成本低。更多还原

【Abstract】 The mineralogical characters of Hongya Pb-Zn ores were described in this paper. According to ore properties,coarse grinding_selective flotation_gravity concentration flowsheet was adapted. Rationalized utilization of these mineral resources was successfully realized. Stability and reliability of this technological flowsheet were confirmed in production practice,and better production index and lower operating cost were achieved.更多还原
