西藏某铜钼矿，由于矿石中存在大量易泥化的脉石矿物，在碎磨过程中产生大量的次生矿泥，导致选矿废水存在难以沉淀的微细粒级矿物颗粒，且残存大量的浮选药剂，导致在铜钼混合浮选阶段混合精选效率较低、现场不易操作等不利影响。通过使用絮凝剂来沉淀微细粒级矿物颗粒，利用高原特有的强烈的紫外线暴晒条件降低COD，经过处理后的废水回用于铜钼混合浮选试验，闭路试验结果表明经处理后的废水净化效果较好，回用对浮选指标的影响较小。

A Tibet Cu-Mo mine hosts a large number of easy prone-argillation gangue minerals, produces large amounts of secondary crushing sludge in the grinding process, leading to the micro-fine particles of mineral grains from dressing wastewater hard to precipitate.And the remnants of flotation reagents result in the low efficiency of hybrid selection and dif-ficulty to operate the flotation.By using flocculants to precipitate the micro-fine particles and using UV irradiation to reduce COD.The treated wastewater reused for the flotation closed-circuit test shows that the effect of the wastewater purification is good.The recycling of the treated wastewater has small impact on flotation index.
