摘　　要：本文针对辽宁凤城硼铁矿资源,应用氧化石蜡皂作为捕收剂、Na2CO3为矿浆pH调整剂、Na2S iO3为硅酸盐矿物抑制剂,进行浮选分离硼镁石矿物的探索研究。结果表明,B2O3品位为9.64%的入选原料,经过浮选可以获得B2O3品位为13.93%、回收率为79.54%的硼精矿;应用Na2S iO3抑制剂对分选指标的影响不明显,进一步提高硼镁石单体解离度是改善分选效果的重要途径。A laboratory flotation study was conducted to reclaim camsellite from Liaoning Fengcheng ludwigite ore with oxidized paraffinum sodium salt as collector, Na2CO3 as pH adjustor and Na2SiO3 as depressant to silicate minrals. The results indicated that, under certain conditions, a concentrate with B2O3 grade of 13.93% and recovery of 79.54% was obtained. Application of Na2SiO3 in this study had on obvious influences on concentration performnce. Increasing further camsellite liberation degree is the key to improve separation effects.
