Flotation Fluorite Phases

Flotation Archives — Page 4 of 35. Flotation separations of various calcium-bearing minerals such as fluorite from calcite and scheelite from calcite and apatite almost always involve the use of sodium silicate, for example. Pure samples of apatite (Durango), calcite (Icelandspar), fluorite, and scheelite were used in this investigation

Natural hydrophobicity and flotation ff fluorite

Hydrophobicity of fluorite and the time of the three phase contact formation influence its flotation. The best flotation is observed in Hallimond tubes while flotation is significantly reduced or absent in laboratory flotation machines. This is very likely a result of relatively long time of the TPC formation and/or low hydrophobicity of

IMPROVING FLUORITE FLOTATION UNDER LOW TEMPERATURE

The flotation of fluorite mineral from ores by using acidized water glass as depressant has been studied for substitution of the commonly used depressant. It was found that the acidized water glass could achieve higher selectivity of fluorite minerals against gangue minerals in the fluorite flotation. The experimental results showed that YF
