甲玛多金属矿选矿厂针对其矿石性质发生的变化，将选别流程进行了调整优化，同时对浮选设备及辅助设备进行了技术改造。改造后，工艺流程比较稳定，各选别作业矿浆循环量平衡，在原矿品位 Cu 0．673％、Mo 0．018％、Au 0．357 g／t、Ag 20．607 g／t 情况下，获得Cu品位23．237％、Mo品位0．422％、Au品位8．998 g／t、Ag品位495．12 g／t的混合精矿，混合浮选回收率为Cu 89．924％、Mo 59．705％、Au 65．780％、Ag 62．666％，浮选技术指标较为理想。
In light of the ore property change in Jiama polymetallic mine,the ore-dressing plant modified the sepa-ration process and at the same time renovated the flotation equipment and auxiliary facilities.After renovation,the flow-sheet is stable,and every stream has a balanced slurry cycling.The flotation effect is satisfactory.Under the condition that Cu grade is 23.237%,Mo is 0.018%,Au is 0.357 g/t and Ag is 20.607 g/t in crude ores,a mixed concentrate with Cu grade of 23.237%,Mo 0.422%,Au 8.998 g/t and Ag 495.12 g/t is obtained and the recovery rates of the mixed flotation are Cu 89.924%,Mo 59.705%,Au 65.780%,Ag 62.666%respectively.The flotation indexes are satisfactory.
