Abstract:This is an essay in the field of mineral processing engineering. Lead-zinc mine is one of the important strategic mineral resources in our country, and it is generally poor, fine and complex. Lead-zinc sulfide deposit is about 90% of total reserves. At present, flotation is the most commonly used method for the beneficiation of lead-zinc sulfide ore, and the selection of flotation reagents plays a decisive role in the flotation process index. In this paper, recent research progress of zinc sulfide flotation reagents is summarized, emphatically introduces the collecting agent, inhibitor and activator, analyzes the future the key research direction of zinc sulfide flotation, finally points out that the microbe as flotation reagents zinc sulfide flotation in the broad application prospect in the future, to achieve efficient vulcanization lead-zinc separation to provide technical and theoretical support.

表 1 硫化铅锌矿常用浮选工艺特点
Table 1. Characteristics of flotation process of lead-zinc sulfide ore
浮选工艺 工艺流程 矿石适用类型 优点 优先浮选 根据可浮性差异进行铅锌分离，先抑锌浮铅，再活化锌，最终得到铅、锌精矿。 可浮性差异大、脉石含量较少，有用矿物呈粗粒嵌布。 流程简单、所得精矿质量高、指标稳定等。 混合浮选 先混合浮选出铅锌精矿，再进行铅锌分离。 可浮性差异小、脉石含量较多，有用矿物呈集合体嵌布。 减少后续研磨成本、减少药剂用量等。 等可浮浮选 将可浮性相近的硫化铅锌一起选别出来，再进行铅锌分离。 适用于包含易浮选和难浮选两部分的铅锌矿物。 药剂用量少、节约能耗，减少药剂后续的不良影响等。 电位调控浮选 通过改变浮选体系的电化学条件来控制矿物表面性质，实现铅锌选择性分离。 复杂多金属低品位硫化铅锌矿 药剂用量少，环境污染小，选择性高等。
