摘要

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 difficulty 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.
