内蒙古某铜铅锌复杂多金属矿的浮选试验研究

摘要

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.%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 1 642.0 g/t, the recovery is 60. 3% ; the zinc concentrate contents In 248. 7 g/t, the recovery is 53.5%. The results showed that this flotation process can treat this complex polymetallic ore effectively.
