Abstract

Interactions between the dissolved mineral species and other mineral surface were investigated using solution chemistry calculation,ζ-potential measurement, AES analysis and flotation tests. It has been indicated that there can be precipitation of scheelite over fluorite in scheelite supernatant at pH>4. The conversion of fluorite into scheelite was detected by AES. Fluorite in the supernatant of scheelite exhibits nearly identical electrokinetic property and flotation behavior with those of scheelite. The selective flotation separation of fluorite from scheelite or vice vasa may be achieved by using selective amphoteric collector for fluorite at pH<4 to avoid surface conversion.
