New insights into the depressive mechanism of citric acid ...

2021-9-1 · Therefore, the research and development of fluorite inhibitors for the flotation of scheelite and fluorite remain an urgent problem. Citric acid (CA) is a water-soluble organic acid. It has a strong metal-ion-complexing ability, it is nontoxic and can easily biodegraded, and it is an environmentally friendly flotation reagent ( Lin et al., 2020 ...

Selective flotation separation of fluorite from calcite by ...

The tailings of scheelite flotation were the feed for fluorite flotation and the flotation stages were carried out using a self-aerated XFD flotation machine (Jilin Exploring Machinery Plant, Jilin, China) with 3.0 L volume for rougher-scavenger flotation. The flotation impeller speed was fixed at 1992 rpm.

The Interaction Force between Scheelite and Scheelite ...

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 surface ...

Reverse Flotation Separation of Fluorite from Calcite: A ...

Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP or H4L) is widely used as an environmentally friendly ...

Comparison of Sodium Oleate and Sodium Petroleum

2021-9-30 · Fluorite, a kind of critical non-metallic minerals, is the primary source of industrial fluorine. Sodium oleate (SO) is commonly used as the collector of fluorite ores. However, because of its some features (such as the low solubility, high solidifying point, and poor dispersion of SO) at low temperatures, it profoundly inhibits its collecting ability as well as the flotation performance ...
