东鞍山难选矿选矿技术探讨

Inquire into the Mineral Processing Technology of Donganshan′S Refractory Ores

对提高东鞍山难选矿浮选指标进行了探讨，主要包括：提高矿浆电位；磨矿时添加合适的药剂（如ＤＦ１）；改变矿浆流变性；选择合适的磨矿环境；浮选前充分搅拌、充气；加入少量的辅助捕收剂ＤＦ２与氧化石蜡皂配合使用。

Investigation has been done on improving the flotation indexes of Donganshan′s refractory ores,which mainly include: to raise the pulp potential;to add appropriate reagents,such as DF1,during grinding;to change the pulp rheological properties;to select suitable grinding environment;to fully agitate and aerify the pulp before flotation;and to add a small amout of auxiliary collector DF2 which will be used in combination with oxidized paraffin soap.
