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.
