| Abstract: | The effect of sodium hexametaphosphate and sodium silicate on the flotation of Yinluo magnesiteore is studied.It was found that the synergism of these two depressors isspecially useful in the removal of dolomite and silicate gangue.The size distribution of flotation feed and its mineral composition were also analyzed.It can beseen that pre-desliming by hydrocyclones can improve the flotation effect and decrease the dosage of depressors. |

| Keywords: | flotation dispersin pulp ondition mixing depression pre-desliming |
