Improving Fluorite Ore Flotation Effect

2.1 Quartz type fluorite ore. The separation of quartz and fluorite achieved by grinding, it is an important factor affecting the flotation of quartz-type fluorite. The ground ore of a coarse size indicates that may have many associated fluorite ore lumps, these lumps may increase the silica content, decrease the flotation effect.

The sulfide ore contained in fluorite is floated with xanthate collector, and then fatty acid collectors float fluorite. In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite concentrate. Mixed flotation of fluorite and barite flotation

Effect Of Flotation Time On Froth Flotation Most of the flotation plants are conducted under normal temperature conditions. However, in production practice, when flotation of sulfide ore, heating the pulp is beneficial to the effect of froth flotation.

The article presents experimental research into intensification of fine-disseminated carbonate-fluorite ore flotation by adding FLOTOL-7,9 agent. It is shown that the optimal agent modes allow the yield of the saleable fluorite product of above 90% CaF2 grade at higher than 60% fluorite extraction.

The flotation separation result of a mixture of fluorite and calcite is shown in Table 1. Whether the depressant is water glass or tannic acid, an increase in the dosage of acid in the mixed depressant can significantly improve the grade of mixed concentrate. The kinds of inorganic acids have no great influence on the flotation results. Table 1.

The present invention provides a method of producing low-cost production fluorite floating selection collectors collecting capacity, water-soluble, dispersible, suitable for room temperature and low flotation fluorite. Fluorite flotation adjusting agent composition. A flotation of fluorite ore processing method, it is granted a patent

The Improvement Effect of Dispersant in Fluorite Flotation . At present, we commonly adopt the flotation method to remove the mineral impurities except fluorite in the fluorite ore to improve the content of CaF 2, among which the dispersion process is a very important technique and the selection of dispersants will have a direct impact on the contents of CaF 2 of the final products In this

The sulfide ore contained in fluorite (fluorspar) is floated with xanthate collector, and then fatty acid collectors float fluorite (fluorspar). In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the

Then, these samples were floated. RESULTS AND DISCUSSION Separation of Molybdenum from Fluorite Flotation of Sulfurized SamplesFirstly, samples of original fluorite ore containing molybdenum were ground, sieved to -100 mesh size, dried at 110 o C and then reacted with gas mixtures containing different amounts of H 2 S + H 2 O for 1 hour at 120 o C.

May 01, · The ore sample used in this work was collected from the feed ore of the fluorite flotation circuit in the Las Cuervas concentration plant. The ore sample consisted of fluorite, quartz, calcite and clay minerals. The head grade for the sample was determined to be 75.08% CaF 2, 5.01% CaCO 3 and 9.69% SiO 2.

Hydrophilic ore particles are difficult to adhere to the bubble, remain in the pulp. For the flotation process, the adhesion degree of ore particles on bubbles has a direct impact on the flotation effect, so improving the degree of bubble mineralization is one of the key factors to improve the flotation process effect.

Apr 24,  · This effect is called a synergistic effect, and the reagent used is called a combined reagent. Combined flotation reagents can improve the flotation effect, so it has been widely used in the flotation and flocculation of metallic sulfide ore, metallic oxide ore and non-metal ore. 2. Why Combined Flotation Reagents Useful?

24/4/ · The separation of quartz and fluorite achieved by grinding, it is an important factor affecting the flotation of quartz-type fluorite. The ground ore of a coarse size indicates that may have many associated fluorite ore lumps, these lumps may increase the silica content, decrease the flotation effect.

Fluorite ore beneficiation methods mainly apopt flotation technology, generally use multiple selection to improve the concentrate grade. Applications. Fluorite ore flotation process can apply to the fluorite ore of high clay content, impurities, minerals and fluorite symbiosis, fine granularity and other useful minerals Khenpo complex.

Selective flotation of fluorite from calcite presents many problems because the two minerals have the same cation, Ca++, in their crystal lattices. to improve the selective depression effect

In order to achieve better flotation effect, Xinhai would add a small amount of sulphide inhibitor to inhibit residual sulfide ore, thus to improve fluorite concentrate grade. 2.Separation between fluorite and barite. In , Xinhai undertook 400tpd fluorite ore dressing plant in Outer Mongolia.

fluorite ore :The beneficiation of fluorite ore is gravity separation and flotation process. The specificity of fluorite flotation: 1. Because industrial making hydrofluoric acid require calcium fluorite content>98% and silica <1%, fluorite flotation generally use 5-7 stages concentration; 2. When the PH of ore pulp is 8-11, the floatability is good.

Using the fatty acid as the collector to collect fluorite ore, and sodium silicate as the inhibitor to inhibit quartz in the fluorite beneficiation process. Less amount of sodium silicate will cause worse inhibition effect, but activates fluorite in the fluorite flotation process. However, over sodium silicate will

At present, we commonly adopt the flotation method to remove the mineral impurities except fluorite in the fluorite ore to improve the content of CaF 2, among which the dispersion process is a very important technique and the selection of dispersants will have a direct impact on the contents of CaF 2 of the final products [7].
