| 摘 要： | 以凡口铅锌矿选矿废水为研究对象, 利用电化学技术考察了不同取样点废水对方铅矿可浮性的影响。结果表明, 铅精水和锌精水中剩余的捕收剂分子能促使方铅矿表面形成黄原酸铅。锌尾水和污水中的某些特殊化学成分使方铅矿表面发生变化, 该部分水的直接回用会对方铅矿浮选产生不利影响。

| Abstract: | Electrochemical technology was introduced to study the floatability of galena in some wastewater samples from different processes of mineral processing plant in Fankou Lead-Zinc Mine. It shows that, the residual collector molecules in the wastewater from the thickening of lead and zinc concentrates can benefit the formation of lead xanthanate onto the surface of galena, yet, some special chemical components in the wastewater from zinc tailings and effluent may induce some surface reactions on galena, and herewith the direct reuse of this water may bring disadvantageous influence on ga-lena flotation. |
