摘　　要：本文以油酸钠为捕收剂,通过氟碳铈矿纯矿物浮选试验,考察了金属离子钙镁铁及矿浆温度对氟碳铈矿可浮性影响及调控。试验研究结果表明,钙、镁、铁离子及矿浆温度对氟碳铈矿的浮选过程均表现出不同程度的抑制作用。通过添加活化剂EDTA、硝酸铅或十二烷基磺酸钠,均可调控受到抑制的氟碳铈矿的可浮性。Through the flotation test of bastnaesite pure mineral,the paper investigated the effects of metal ions,incuding calcium、magnesium、iron in the pulp and slurry temperature on the floatability of fluorocarbon cerium ore and regulaiton,with ssodium oleate as the collector.The experimental results showed that calcium、magnesium、iron ions and slurry temperature had different degrees of inhibition on the flotation process of bastnaesite with sodium oleate as collector.The floatability of inhibited bastnaesite by calcium and magnesium ions can be activated by EDTA、lead nitrate、sodium dodecyl sulfonate as activators.
