The gold tailings from Gold Fields containing low scheelite values has a compled mineralogy with hornblende, quartz, arsenopyrite and calcite as major gangue minerals. The most difficult problem in scheelite flotation is not the removal of the siliceous or sulphide gangue, but the separation of Scheelite and calcite minerals which have similar surface propertiesLearn More
In this paper, the effect of acidified water glass (AWG) on the flotation separation of scheelite from calcite using mixed collector of dodecylamine (DDA) and sodium oleate (NaOL) was investigated. The flotation results show that AWG could selectively depress the flotation of calcite at pH 7. A series of mechanism experiments confirm that the chemisorption of AWG on calcite surface is moreLearn More

Oct 13, 2018 · Preliminary studies were made on the use of flotation rate differences to effect a separation of scheelite, fluorite and calcite. Using starvation quantities of reagents (at, or slightly above, the incipient sodium oleate collector concentration required for nearly complete flotation) mineral flotation rates were determined as a function of pHLearn More
Flotation separation of scheelite from calcite using mixed collectors. International Journal of Mineral Processing, 169, 106-110. Zhang W., Honaker R.Q., Groppo J., (2017).

Scheelite and fluorite are important industrial minerals used as raw materials to produce spaceflight items, catalysts, ceramics, optical glass, and fine chemicals .However, Flotation separation of scheelite from fluorite is difficult because of the existence of the same cation in the minerals and similar physicochemical characteristics such as solubility, hardness, specific gravity, and PZCLearn More
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.sale mineral separator jig machine for gold. So we could remove zircon etc. into froth product thus cleaning scheeliteLearn More
The use of saline sodium silicate as a depressant can achieve the flotation separation of scheelite from calcite. The zeta potential results and adsorption studies showed that the pre-adsorption of saline sodium silicate only interferes with the adsorption of benzohydroxamic acid on calcite surface; this is the main reason for the selectiveLearn More
Apr 16, 2020 · The flotation separation of scheelite from fluorite, apatite, and calcite has been intensively investigated over the past decades and remains, in the twenty first century, one of the most challenging problems in the froth flotation fieldLearn More
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.magnetic separator for separation of weak magnetic ore beneficiation popular.

Apr 13, 2020 · The separation of scheelite and cassiterite can be carried out by electric separation or flotation. During flotation separation, scheelite is captured with fatty acids, and cassiterite is suppressed with water glass. When scheelite contains aluminum, because molybdenum has good floatability, molybdenum ore can be floated first, and then scheeliteLearn More
The mechanism of the formation of the hydrophobic agglomerate in fine scheelite flotation was studied using zeta potential measurement, contact angle measurement, optical microscope measurement, and atomic force microscopy (AFM) colloid probe technology. Zeta potential measurement results confirmed the adsorption of sodium oleate on scheelite, fluorite, and calcite surface and surfaceLearn More
The separation of scheelite from sulfide ore and other non - metallic ore should be paid attention.
