This work introduces a feasible mineral processing method for the beneficiation of low grade and complex scheelite using the X-ray transmission (XRT) …
This paper proposes luteolin (LUT) as a novel depressant for the flotation-based separation of scheelite and calcite in a sodium oleate (NaOL) system. The suitability of LUT as a calcite depressant is confirmed through micro-flotation testing.
Owing to the depletion of wolframite, the focus of tungsten extraction has gradually shifted to scheelite. However, separating the associated minerals (e.g., apatite, fluorite, and calcite) and scheelite is challenging because their surface physicochemical properties are similar to those of scheelite. Fortunately, researchers have made …
• Novel concepts and specific processes have been studied to increase flotation efficiency of fine and very scheelite and wolframite. • Combined beneficiation …
For example, it was found that tin can be enriched with wolframite to obtain a relatively low-grade wolframite – scheelite mixed ore with high tin content after the flotation process. A beneficiation study indicated that beneficiating wolframite-scheelite mixed ore with approximately 40% WO 3 content can guarantee a higher metal recovery ...
In this work, N-tetradecyl-isopropanolamine (NTIA) is synthesized and used as a new collector on the flotation separation process of scheelite from calcite to further improve the efficiency of the selective flotation.
The rate of the scheelite flotation process with an hydroxyhydryl sorbent tending to micelle formation, depended on the content of the flotation-active form of the sorbent in the liquid phase of the pulp, and its distribution between the mineral
In industrial practice, hydrodynamic cavitation (HC) is commonly triggered by jetting either reagent solution or pulp. Although both methods can enhance mineral flotation, are their roles the same? There are few research studies in the field, which severely limits our understanding on mineral flotation combined with HC. Therefore, in …

This similarity complicates scheelite beneficiation. Consequently, the selective separation of scheelite from calcite is crucial for the efficient use of scheelite resources. Flotation is widely employed as a technique for separating scheelite from calcite [4], [5].
The efficient separation of scheelite from apatite is still a big challenge by using froth flotation because of their similar surface's properties. In…
The gravity concentration and magnetic separation techniques are predominantly practiced in wolframite beneficiation, while gravity concentration followed by froth flotation is the key route in the scheelite beneficiation.

The flotation separation of scheelite, which is hindered by its interface similarity with calcium-containing minerals, remains a worldwide challenge. Achieving precise regulation of interfacial physicochemical properties constitutes the scientific …
The fine scheelite flotation using garnet and glass beads as agitation medium was investigated through slurry rheology and froth property analysis. The apparent viscosity of fine scheelite, calcite and quartz (−20 μm) slurry were measured and the corresponding scheelite flotation behaviours, froth water recovery and froth height …
