某黄金矿山针对其规模的不断扩大，但受到场地的限制，配套设备不能无限制扩大，造成浮选矿浆浓度高、粒度粗等问题，进行了一系列工艺参数的优化及相应技术改造，确定了适宜的药剂制度，保证了较高的金回收率。技术改造后，该矿山选矿厂累计处理矿石量899755 t，获得浮选尾矿品位低于0．115 g/t，富集比19．16倍，金浮选回收率95．34％的较好指标。

One gold mine expands in scale but confined by terrains the auxiliary facilities can not go with it,resul-ting a series of problems like high concentration pulp and coarse granularity in flotation.In order to deal with that,opti-mization of process parameters and their renovation measures are carried out,proper agent system is selected,guaran-teeing relatively high gold recovery rate.After renovation,accumulated treatment amount of ores reach 899 755 t,ob-taining a low tailings grade of 0.115 g/t,enrichment ratio of 19.16 and gold flotation rate of 95.34 %.
