【摘要】:銅鉬礦的銅鉬分離一直是國內(nèi)外銅鉬礦山的研究重點(diǎn),銅鉬礦(主要是硫化礦)一般通過混合浮選得到銅鉬混合精礦,之后進(jìn)行分離。絕大多數(shù)的礦山采用抑銅浮鉬來實(shí)現(xiàn),烏山礦工業(yè)生產(chǎn)中也采用此工藝。烏山礦在銅鉬分離中通過添加有機(jī)和無機(jī)抑制劑配合使用來實(shí)現(xiàn)銅鉬有效分離,在工業(yè)生產(chǎn)中采用電位控制法,用Na HS調(diào)節(jié)氧化還原電位,可以使抑制劑8371達(dá)到良好的選擇性,穩(wěn)定了鉬精礦的品位和含銅、鉬的作業(yè)回收率,在入選鉬品位由1.89%降低到1.65%的不利條件下,鉬精礦的鉬品位較試驗(yàn)前47.52%提高到48.67%;鉬精礦中含銅由試驗(yàn)前的1.46%降低到1.09%;鉬的回收率由試驗(yàn)前的83.77%增加到87.35%,試驗(yàn)取得了較好的效果。
[Abstract]:The separation of copper and Mo from copper-Mo ore has always been the focus of research at home and abroad. Copper-Mo ore (mainly sulfide ore) is generally obtained by mixed flotation, and then separated. Most of the mines are realized by inhibiting copper floating Mo, and this process is also used in the industrial production of Wushan Mine. In Wushan Mine, the effective separation of copper and Mo can be realized by adding organic and inorganic inhibitors in combination with each other. In industrial production, the redox potential can be adjusted by using potential control method and Na HS, so that the inhibitor 8371 can achieve good selectivity. The grade of Mo concentrate and the recovery rate of copper and Mo were stabilized. Under the unfavorable condition of decreasing the grade of Mo from 1.89% to 1.65%, the grade of Mo concentrate was increased to 48.67% compared with 47.52% before the test. The copper content in Mo concentrate decreased from 1.46% to 1.09%, and the recovery of Mo increased from 83.77% to 87.35%. Good results were obtained.
