China Tungsten Industry. This paper reviews the development of Scheelite flotation technique in recent years.Scheelite flotation solution chemistry,flotation process,flotation reagent,micro-grained scheelite flotation and equipment are the four directions of theoretical and technology development.Some counter-measures are also put forward.
In most scheelite flotation plants, the flotation recoveries are merely 60–85%, such as Cantung mine (75–79%) in Canada, 2 Shizhuyuan mine (65%) in …
The poor collecting performance of fatty acids at low temperatures is a problem in mineral flotation. In this study, the floatability of scheelite at 283 K was studied using sodium oleate and binary mixtures of sodium oleate and lauryl alcohol polyoxyethylene ether (MOA-9) as the collector, and interactions between the two surfactants at 283 K were …
Meanwhile, when Pb-water glass and Al-Na 2 SiO 3 are used as combined inhibitors, the metal silicate polymers adsorb more on the calcite surface and less on the scheelite surface [5,20]. The flotation rate of scheelite can also be improved by using a combination of Pb-BHA and Fe-BHA collectors [11,21,22]; however, their widespread application ...
This paper reviews the scheelite flotation reagents, including collectors and regulators, and introduces recent research progress on the mechanisms for the …
Flotation separation of scheelite from calcite is difficult due to the similarities in their surface properties. In this work, the flotation behavior of scheelite and calcite using oxidized paraffin soap(OPS), benzohydroxamic acid(BHA) and the mixed OPS/BHA collectors was investigated through micro-flotation experiments. The flotation results of …
An efficiently optimized reagent regime was investigated to improve scheelite heating flotation. The scheelite grade and recovery in the plant were significantly improved by 5% and 6%, respectively, which remarkably augmented the economic profit by $260,000 per month. The interaction mechanisms of sodium sulfide …
Despite having lower reserves than scheelite, wolframite has always been the primary source of tungsten resources due to its high ore gradation and easy mining and processing [8,9]. With expansion of the economy, the easily accessible wolframite deposits are gradually being depleted, making efficient utilization of scheelite resources crucial ...
Improved Flotation Separation of Scheelite from Calcite by Sulfomethylated Kraft Lignin. Low-grade and high-reserve scheelite, which is associated with calcite, has similar surface properties that cause difficulty in separation. In this study, sulfomethylated kraft lignin (SMKL) was used….
Herein, we provide a theoretical basis for developing scheelite flotation depressants. 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 ...

ABSTRACT Scheelite and calcite are usually intergrown calcium minerals that are separated via froth flotation. However, their selective separation remains difficult because of their similar surface properties. 2-phosphonobutane −1, 2, 4-tricarboxylic acid (PBTCA or H5L) is widely used in water treatment due to its low phosphorus content and …
