Flotation of fluorite from ores by using acidized water

2013-5-1  The flotation kinetics of fluorite from the ore with the actual and new schemes was illustrated in Fig. 6. Here, only rougher flotation was performed. The new scheme showed improved fluorite recoveries when compared to the actual scheme. The new scheme reached the maximum fluorite recovery around 4 min, while the actual scheme took 6 min.

IMPROVING FLUORITE FLOTATION UNDER LOW

2020-11-29  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 collector has high selectivity in the flotation of fluoride for low

Ore-Forming Fluids of Vein-Type Fluorite Deposits of

2010-7-6  Three successive stages of mineralization were distinguished on the basis of vein chronology, REE data, and fluid-inclusion study in fluorite ores. These stages generally display slightly fractionated REE patterns (La/Yb = 1.4 to 14), with REE behavior given by a relatively stronger LREE fractionation with respect to HREE.
