摘要：
It has been carried out an study about the influence of some variables in the flotation of precipitated phosphates, using sodium oleate as collector agent. It has been analyzed the effect of the pH in the flotation bath, the concentration of the collector agent and the variation of bath temperature. The obtained results indicate that an increase in the temperature raises considerably the mineral recuperation percentage, and the result is that those percentages are higher as higher is the employed oleate concentration. At the same time, this increase in the bath temperature increases the richness in P2O5 of the flotated mineral.
