【摘要】 针对甘肃某混合型铜矿,氧化率高、易泥化、嵌布粒度不均匀的特点,采用硫化-氧化铜矿物混合浮选的工艺方案进行了矿石浮选试验研究。试验研究结果表明,在适宜的磨矿细度和药剂制度下,采用试验确定的闭路试验流程处理该矿石,可获得铜品位为23.98%、回收率为85.09%的良好指标。更多还原

【Abstract】 According to mineral characteristics of high oxidation rate,easy slimming and uneven dissemination size for a refractory copper bulk ore,the process flowsheet of bulk flotation for sulfide and oxidized copper ore was adopted. Test results indicate that under the conditions of appropriate grinding and reagent system,a copper concentrate containing Cu 23. 98%with recovery of 85. 09% can be obtained.更多还原
