摘要
叙述了五龙沟金矿难浸金矿石工艺矿物学特征,通过室内、外生物氧化试验证明,认为浮选+精粉生物氧化是该类难浸金矿提金的有效途径。经过生物氧化的金精粉金的浸出率可由原来的7.1%提高到93%左右。
The paper introduces the character of process mineralogy of refractory ore in Wulonggou gold mine. The test results proved that the flotation ＋ fine bioleaching is a efficient path. And the leaching recovery increased from 7.1% to 93%.
