内蒙古某铜铅锌复杂多金属矿的浮选试验研究

试验矿样取自内蒙古某地的铜铅锌复杂多金属矿,原矿含Cu 0.25%、Pb 2.53%、Zn 4.47%,并且伴生Ag 92.5 g/t、In 42.5 g/t,研究了该矿石的浮选工艺以及在浮选过程中各种药剂的用量,最终得到铜精矿中含Cu 17.62%、回收率达到58.26%;铅精矿含Pb 66.55%、回收率高达90.39%;锌精矿含Zn 48.12%,回收率90.29%;与此同时,铅精矿含Ag达到1 642.0 g/t、回收率60.3%,锌精矿含In达到248.7 g/t、回收率达到53.5%。结果表明,此浮选工艺可有效处理该复杂多金属矿。

Flotation Experiment Study on a Copper-Lead-Zinc Complex Polymetallic Ore in Inner Mongolia

The experiment sample is taken from a copper-lead-zinc complex polymetallic deposit in Inner Mongolia,there are 0.25% Cu,2.53% Pb,4.47% Zn in the raw ore,and it also associated with 92.5 g/t Ag and 42.5 g/t In,the flotation process of this ore and also the dosage of agents which used in the flotation process is researched,the copper concentrate contents Cu 17.6%,and the recovery can be reached to 58.26%;the lead concentrate contents Pb 66.55%,the recovery reach up to 90.39%;the zinc concentrate contents Ag ...
