摘要
以纯矿物和实际矿石研究了Y-89新型高效捕收剂对含次生铜矿物的难选铜硫矿石的浮选行为。研究结果表明,在石灰造成的高碱条件下,采用Y-89优先浮选铜硫矿石中的铜,可获得铜品位16.89%、铜回收率80.36%的铜精矿,与黄药相比,铜精矿品位提高了1.81%、铜回收率提高了6.13%,证明Y-89在高碱条件下的选择性和捕收能力均高于黄药。
In this paper,the flotation behavior of high-effective collector Y-89 to hard-processing copper-sulfur ores with secondary copper is studied by pure mineral and ores. It has been shown that the copper concentrate with grade of copper 16.89%, recovery of copper 80.36% is got by using Y-89 under the high alkaline of lime. Compared with xanthate, the grade of copper is improved with 1.81%, and the recovery improvement of copper is 6.13%. It has been proved that under high alkaline condition the selectivity and collecting ability of Y-89 is higher than xanthate.
