Feb 15, 2021 For fluorite ores, fatty acid and sodium silicate are frequently used as a collector and depressant, respectively , , . Innovations and combinations of various additives comprise a significant share of the advanced investigations in fluorite flotation , , . In some situations, effective flotation could be realized with only one kind of additiveget price
In this study, we aimed to collect molybdenum and fluorite in separate phases and to increase flotation yield. Therefore, before the flotation, the sulfurization process was made in order Vol.5, No.2 Enrichment of Molybdenum and Fluorite 105 to change the ore structure and surface properties [7, 8]get price
Having thus described our invention, what we desire to secure by Letters patent and hereby claim is 1. In a flotation process for the recovery of fluorite from clay-containing ores, the improvement which comprises, prior to carrying out conventional flotation, conditioning a flotation slurry by treating said slurry for a period of from about 1 to 10 minutes with from about 100 to 200 grams perget price
This expectation is revealed by flotation recovery curves for fluorite and calcite with calcium dioleate as collector . As shown in Figure 3, flotation of fluorite is quite strong with the calcium dioleate collector colloid, whereas such is not the case for calcite, The tendency for attachment of the calcium dioleateget price
The invention discloses a collector for the floatation of fluorite at a low temperature. The collector comprises the following raw materials in weight portion: 35 to 45 portions of fatty alcohol polyethenoxy ether carboxylic acid sodium, 40 to 50 portions of sodium cetanesulfonate, and 8 to 12 portions of fatty acid methyl ester sodium sulfonateget price
Mar 25, 2015 Abstract. Different dispersants were added in the dispersion process to improve the efficiency of fluorite flotation. The types and dosage of dispersant on the improvement of fluorite flotation were investigated; when the sodium polyacrylate (SPA) was used as the dispersant and its addition is 0.5%, the concentrate grade of CaF 2 increased from 90% to 98% and the fluoriteget price
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached airget price
Reverse cationic flotation batch tests were conducted using 1kg of fluorspar tailings in 2.5l Denver D12 flotation cell at pulp density of 40% solids, impeller speed of 1000rpm and air flowrate of 60%. Before flotation, the pulp was first conditioned with starch for 4min and then conditioned with collector for 4minget price
Hydrophobicity of fluorite and the time of the three phase contact formation influence its flotation. The best flotation is observed in Hallimond tubes while flotation is significantly reduced or absent in laboratory flotation machines. This is very likely a result of relatively long time of the TPC formation and/or low hydrophobicity ofget price
A flotation separation method for fluorite and dolomite in acid condition, comprise the steps: to adopt sulfuric acid do pH value adjusting agent, acid fuchsin and ironic citrate as dolomite and other impure mineral inhibitor, make the collecting agent of fluorite mineral with vegetable oil acid.Adopt the present invention can make fluorite mineral and dolomite and other impure mineralget price
In typical flotation the solid phase is in a particulate form, which is attached to a bubble, both travelling to the froth phase. The surface of particle is usually rough. The shape and roughness of particles are determined by the ... flotation of fluorite depend on its origin, color and pH. Depending on the surface structure of mineral, pH andget price
Fluorite flotation process is one of the most important processes in fluorite flotation, and it is widely used. According to statistics, more than 90% of fluorite materials are treated by this process. Compared with other beneficiation methods, flotation is economical and effectiveget price
Apr 24, 2019 2 Flotation Processes of 4 types of associated fluorite. Just as is the case with almost ore processing and non-metal beneficiation, the concentrate fluorite is extracted by crushing, sieving, grinding, grading, flotation, filtration, drying, etc. How to realize the high-efficiency sorting of associated fluorite ore is a real problem in theget price
Apr 01, 2021 The next stage, i.e., the flotation of the mixed concentrates, has two options: a) regular flotation, where the fluorite is floated using fatty acid as the collector, while barite is depressed by dextrin, tannin or malysite; b) reverse flotation, where hydroxy sulfate ester is used as the collector to float the barite, while the target mineral, fluorite, remains in the tailing [172,173]get price
Hydrophobicity of fluorite and the time of the three phase contact formation influence its flotation. The best flotation is observed in Hallimond tubes while flotation is significantly reduced orget price
containing fluorite were collected with fairly high yields in different phases by the flotation of the sulfurized ore. In the optimum flotation conditions, the Mo, Pb, Cu and Zn were obtained over 95 % yields and approximately 6 % fluorite passed into concentrate phase. Mo and Cu containingget price
Fluorite (CaF 2) is by far the most important fluorine-bearing mineral phase in the Earth’s crust. It is mostly used for manufacturing glass, cement, fillers, and hydrofluoric acid, and as a flux in steel-making in various industries [ 1, 2, 3 ]get price
May 01, 2013 1. Introduction. Fluorite flotation is usually realized with sodium lignosulfonate as depressant and fatty acid as collector at a high pH (Crozier, 1992, Ayhan et al., 2006).In the case where feed ores contain a significant amount of fine particles, the sedimentation rate of fine particles was found to be significantly slow due to the effective dispersion of the fine particles whenget price
Jul 26, 2018 The flotation tests of binary mixed minerals showed that the selectivity of SNLS for fluorite was higher than that for scheelite at pH 9.0 and a low dosage of 1.1get price
