Chat Online· Scheelite flotation has run into serious difficulties when it requires separation of scheelite from a carbonaceous gangue. Other calcium-bearing minerals such as calcite apatite and fluorite being semi-soluble salts all exhibit similar flotation properties as scheelite and usual collectors like fatty acids are too unselective for this purpose.
Chat OnlinePA-Na is an ideal inhibitor for the flotation separation of scheelite from fluorite. PA-Na is a complex of polyelectrolyte particles and can dissociate into low-molecular-weight ions (Na ) and polymer ions when the compound is dissolved in an aqueous solution. The polymer ions containing numerous carboxylate ions are multivalent ions.

Chat OnlineFloatability of scheelite calcite and fluorite using Pb–BHA as the collector (CBHA = 2.0 10 −4 mol/L CPb = 2.0 10 −4 mol/L and Cterpineol = 12.5 μL/L). PASP was added as a depressant into the Pb–BHA flotation to increase the difference with respect to the recovery of scheelite and calcite.
Chat Online· The large dosages and high price of BHA greatly increase the cost of flotation which is not conducive to industrial production. Small molecular organic depressants are also increasingly used in scheelite flotation such as citric acid tartaric acid and tannic acid etc. (Zhang et al. 2017). In recent years polymer depressants have become more and more widely used in flotation.

Chat OnlineIntroduction. Scheelite particles are brittle and easily overground in the grind process 1 . As a result there are always a large number of micro-granular slimes in the scheelite pulp which weakens the flotation environment and leads to the loss of the valuable minerals 2 .
Chat OnlineSulfides flotation is a process to remove sulfides mineral such as molybdenum (molybdenite MoS 2) in ores before the scheelite flotation process because they adversely affect the grade and recovery of concentrate in scheelite flotation. In this process 150 g/t of KAX and 50 g/t of MIBC were used as a collector and frother respectively.
Chat Online· The results of investigations into increasing the contrast of process properties of calcite and scheelite due to the combined application of water glass with salts such as sulfates of aluminum zinc iron magnesium mixtures of water glass and calcium chloride sodium carboxymethyl cellulose (CMC) combinations of sodium oleate with low-polar compounds (neonol and fatty iso-alcohols) and
Chat Online· The similar floatabilities of calcium minerals and the huge difference between scheelite and wolframite have resulted in difficulties during their separation by flotation in Shizhuyuan Mine. In this study novel collectors lead complexes of benzohydroxamic acid (Pb–BHA) were introduced to modify the surface properties of scheelite and wolframite thereby effectively and selectively
Chat OnlineA flotation process for recovering scheelite (calcium tungstate) from a low grade slimey ore containing other calcareous minerals such as calcite is described.

Chat Online· So we are doing flotation of sulphides not scheelite flotation. We use butyl potassium xanthat and T-91 reagents. We maintain pH at 2-3 in order to depress scheelite. The best solution for us would be a reagent(s) that we could add after sulphide flotation is exhausted. So we could remove zircon etc. into froth product thus cleaning scheelite.

Chat OnlineThe main challenge in scheelite flotation lies in the contamination of the concentrate by other calcium-bearing minerals mainly calcite. To remedy this problem sodium silicate is frequently used as a depressant. According to the literature one hypothesis for the mechanism of water glass consists in its absorption onto calcite through colloidal silica formation preventing hydrophobization
Chat Online· The main objective of this paper is to define the effect of energy input (EI) on the flocculation process and flotation rate of fine scheelite. A reagent scheme for shear flocculation was determined by basic flotation behavior of fine scheelite (less than 10 µm) in contrast to that of coarse scheelite (larger than 10 µm). A four-baffle cylindrical tank with a four-blade impeller was used to facilitate EI by
