摘要
羊拉露采硫化铜矿石原矿品位低,矿物间共生关系复杂、铜矿物嵌布粒度细。根据矿石特点,本研究将矿石细磨至-400目95%,以使铜矿物充分解离,获得了铜精矿含铜17.15%,回收率79.54%的指标。
The raw copper sulphide ore of Yangla open pit is characterized by low-grade, complex mineral intergrowth and fine dissemination grain of copper mineral. According to the ore characteristics, in this research, the ore is fine grinded to -400 mesh 95% , so that the copper mineral is fully liberated, the concentrate grade of 17.15% Cu and the recovery of 79.54% can be obtained.
