锡铁山浮选流程方案比较研究分析

Comparison and analysis of flowsheet of flotation process in tin Tieshan

根据技改的要求,要求新建选矿厂设备大型化、自动化、现代化。目前选矿厂磨浮车间设备小、系列多,势必要被淘汰新建。目前,西部矿业股份有限公司锡铁山分公司选矿厂的浮选流程分Ⅰ、Ⅱ、Ⅲ系列为"铅优先浮选,锌硫混浮再分离流程"、Ⅳ系列为"铅、锌顺序优先浮选流程"。依据现场实际生产指标,本次对"铅优先浮选,锌硫混浮再分离流程"、"铅、锌顺序优先浮选流程"进行了综合比较。

According to the requirements of technical transformation, the new concentrator will require large-scale equipment, automation and modernization. At present, the grinding workshop in concentrator is small and has a large number of series, which will inevitably be eliminated and newly constructed. At present, the flotation process of western mining Limited by Share Ltd Tieshan branch Tin concentrator I, II and III series as ＂lead flotation, zinc and sulfur mixed flotation separation process＂, ＂Series IV lead and zinc flotation process priority＂. According to the actual production target, this paper makes a comprehensive comparison of ＂lead preferential flotation, zinc and sulfur mixing floating separation process＂ and ＂lead and zinc sequential priority flotation process＂.
