The Effect Of Heating On The Separation Of Scheelite And Calcite And Fluorite Flotation And Its Mechanism

Heating flotation scheelite has a long history, since the 1940s, the Soviet union dressing experts Peterov invention after have been used for many years, scheelite heating flotation method for all types of scheelite the adaptability of the stone is very strong, so this paper will research the heating flotation.Single mineral tests have confirmed that the sodium oleate,731 oxidation paraffin soap,GYR have strong collecting ability for scheelite, calcite and fluorite when they were used alone. their collecting ability is very close. In the acid condition,731 oxidation paraffin soap and GYR can separate scheelite and fluorite by reverse flotation separation.Use it only in combination with GYR and sodium oleate combination of collector in certain proportion cases to show scheelite to ensure recovery calcite and fluorite flotability is slightly better.And other combination did not separate then. In combination with or use of collector can from calcite and fluorite is to separate the scheelite.Heating flotation condition test showed that, in the heating flotation condition, the heating temperature and heating time dialogue the recovery of scheelite more influence, with heating mixing when an increase in the amount of sodium silicate, the recovery of scheelite would be gradually reduce. In heating conditions, to affect the key calcite and fluorite is sodium silicate.For the two artificial mixed minerals about scheelite and calcite, scheelite and fluorite heating flotation tests.By artificial mixed minerals' heating temperature test,heating mixing sodium silicate dosage test and heating mixing time trial, explore the factors heating flotation respectively the grade and recovery of scheelite.Using infrared spectroscopy testing technology of collector of scheelite and calcite and fluorite flotation system the effect and its role in mineral surface product for a preliminary analysis.
