氧化铅锌矿浮选法研究进展

随着易选硫化铅锌矿石资源的日渐减少,市场对铅锌金属的强烈需求推动了难选氧化铅锌矿石浮选技术的进步。为了系统展示难选氧化铅锌矿石浮选技术的进展,从硫化钠硫化浮选法和硫磺硫化浮选法等2方面总结了硫化浮选技术的进展情况,从重选-浮选联合工艺和选冶联合工艺等2方面总结了联合工艺技术的进展情况,从絮凝浮选法、螯合剂浮选法、组合捕收剂浮选法和组合抑制剂浮选法等4方面总结了基于新药剂的浮选技术进展情况,最后对氧化铅锌矿石浮选技术发展的方向展望。

Progress on Oxidized Lead-Zinc Ore Flotation Methods

With the decrease of free-milling lead-zinc sulfide ore resources， the intense demand of market for lead-zinc metal has made the progress on flotation technology of refractory lead-zinc oxide ore. In order to systematically present the progress of flotation technology of refractory lead-zinc oxide ore， the progress of sulfidation flotation technology was summarized from two aspects， including sodium sulfide vulcanization and sulfur vulcanization flotation method. The progress of combined process was summarized from two aspects， including gravity-flotation technology and dressing-metallurgy combination technology. Four aspects， including flocculating flotation， chelating agent flotation， combined collector flotation and combined inhibitor flotation were summarized based on new reagent. Finally， the development direction of flotation technology of lead-zinc oxide ore was prospected.
