摘　　要：针对灵宝黄金某冶炼厂焙烧金精矿浸出流程矿物单体解离度不够、浸出指标不理想的问题,首次将艾砂磨机应用于焙烧矿细磨领域。结果表明,采用艾砂磨机开路细磨,将焙烧滤饼造浆细磨至-38μm粒级占96%后氰化浸出,尾渣金品位由1.72 g/t降至1.42 g/t,综合经济效益增加815.68万元/年。Aiming at the problems of insufficient dissociation degree of mineral monomer and unsatisfactory indices in the leaching process of roasted gold ore in a smelter of Lingbao Gold Group Co Ltd,an ALC mill,for the first time,was applied to fine grinding of roasted gold ore.The results show that with ALC mill used in an open⁃circuit fine grinding,the filter cake pulped and then milled to a fineness of-38μm 96%before cyanide leaching,the final cyanide tailings can have its gold grade reduced from 1.72 g/t to 1.42 g/t.As a result,the comprehensive economic benefit can be increased by 8.1568 million yuan per year.
