针对某铅锌矿次生泥含量高,铅锌共生关系紧密,浮选难取得合格精矿等问题,开展了工艺流程试验研究。在原矿含铅1.33%、锌2.34%时,通过使用自主研发的抑制剂CD-3、起泡剂CF-1,铅浮选作业采用粗精矿再磨,全流程闭路试验获得铅精矿含铅52.88%、锌7.13%,回收率85.34%;锌精矿含锌50.61%、铅1.16%,回收率83.77%的良好选矿指标,解决了原矿获得合格精矿难和回收率低等问题。 Aiming at the problems such as the high content of secondary mud in lead-zinc mine, the close symbiotic relationship between lead and zinc, and the difficulty in obtaining flotation for qualified concentrate, etc., the technological process test was carried out. In the raw ore containing lead 1.33%, zinc 2.34%, by using the independent research and development of inhibitors CD-3, foaming agent CF-1, lead flotation operations using crude concentrate regrinding, the whole process of closed-end test lead concentrate Lead 52.88%, zinc 7.13%, recovery rate 85.34%; zinc concentrate 50.61% zinc, lead 1.16%, recovery 83.77% of the good beneficiation indicators, to solve the ore to obtain qualified concentrate difficult and low recovery problems.
